Abstract
In addiction, risk factors for craving and use include stress and drug-related cues. Stress and cues have additive or more-than-additive effects on drug seeking in laboratory animals, but, surprisingly, seem to compete with one another (ie, exert less-than-additive effects) in human laboratory studies of craving. We sought heretofore elusive evidence that human drug users could show additive (or more-than-additive) effects of stress and cues on craving, using ecological momentary assessment (EMA). Outpatients (N=182) maintained on daily buprenorphine or methadone provided self-reports of stress, craving, mood, and behavior on electronic diaries for up to 16 weeks. In three randomly prompted entries (RPs) per day, participants reported the severity of stress and craving and whether they had seen or been offered opioids, cocaine, cannabis, methamphetamine, alcohol, or tobacco. In random-effects models controlling for between-person differences, we tested effects of momentary drug-cue exposure and stress (and their interaction) on momentary ratings of cocaine and heroin craving. For cocaine craving, the Stress × Cue interaction term had a positive mean effect across participants (M=0.019; CL95 0.001–0.036), denoting a more-than-additive effect. For heroin, the mean was not significantly greater than 0, but the confidence interval was predominantly positive (M=0.019; CL95 −0.007–0.044), suggesting at least an additive effect. Heterogeneity was substantial; qualitatively, the Stress × Cue effect appeared additive for most participants, more than additive for a sizeable minority, and competitive in very few. In the field, unlike in human laboratory studies to date, craving for cocaine and heroin is greater with the combination of drug cues and stress than with either alone. For a substantial minority of users, the combined effect may be more than additive.

Introduction
Stress and drug cues are well-established factors in maintaining drug use and precipitating relapse. Laboratory-animal studies show that the likelihood of drug-seeking behavior is increased by acute stressors (eg, tail pinching, etc) and by cues and contexts associated with drug-taking (Bossert et al, 2013; Cleck and Blendy, 2008; Crombag et al, 2008). In humans, stress and drug cues can increase craving, as demonstrated in studies conducted in the laboratory (Fox et al, 2008; Jobes et al, 2015; Ray et al, 2013; Schmidt et al, 2014) and in studies using ecological momentary assessment to collect data in drug users’ natural environments (Epstein et al, 2009; Preston and Epstein, 2011). Furthermore, reactivity to stress and drug cues has been shown to predict relapse (Back et al, 2010; Kosten et al, 2006; Sinha et al, 2006).
Evidence is growing that the effects of stress and drug cues on addiction are not independent. Consistent with the overlapping neurocircuitry of stress and addiction in laboratory animals (Fosnocht and Briand, 2016; Koob and Volkow, 2016; Mantsch et al, 2014), there is overlap in the interoceptive, hormonal, and physiological effects of stress and drug-associated cues in humans (Bergquist et al, 2010; Sinha et al, 2003). Perhaps even more problematic for treatment and relapse prevention is that stress and drug use interact over time to increase vulnerability to continued drug taking. Experimental evidence supports the idea that stress reactivity is altered in substance users and that combined exposure to stress and drug cues produces especially pronounced neurophysiological changes, craving, and drug seeking (Fosnocht and Briand, 2016; Koob and Volkow, 2016; Mantsch et al, 2014; Robinson and Berridge, 1993). Discussing their incentive-sensitization theory of addiction, Robinson and Berridge (1993) predicted that, because both stress and drug use activate and sensitize dopamine systems, stress will ‘magnify’ craving induced by drug-associated cues. Stress has since been shown to exacerbate cue-induced drug-seeking in the rat reinstatement model (Banna et al, 2010; Buffalari and See, 2009; Feltenstein et al, 2011).
Evidence that stress and cues can combine to exacerbate craving in humans, however, has been harder to find. In human laboratory studies, tobacco smokers, marijuana users, dependent drinkers, and prescription-opioid users exposed to either stressors and drug cues reported increases in craving, but none of the studies succeeded in showing that the combination induced greater craving than either of the two alone (Back et al, 2015; McRae-Clark et al, 2011; Ray et al, 2013; Thomas et al, 2011). Moran-Santa Maria et al, 2014 showed potentiation of craving in women, but not men, given yohimbine as a stressor before exposure to cocaine-paraphernalia cues. In an fMRI study, Dagher et al, 2009 demonstrated stress-increased neural responses to cues in smokers, but the increase was not reflected in self-reported craving. To our knowledge, a stress-induced exacerbation of cue-induced craving in both men and women has been shown only for the odor of chocolate (Pool et al, 2015).
Another approach to studying drug craving, and its relationships with stress and cues, is ecological momentary assessment (EMA), a data collection methodology in which participants make self-reports on electronic diaries as they go about their normal activities. EMA studies have shown a strong relationship between stress and craving when both are assessed at random times in participants’ natural environments (Epstein et al, 2009; Preston and Epstein, 2011). EMA also provides the opportunity to examine cue and stress exposure in context, as participants can be asked to report on their surroundings and activities as well as their moods.
We conducted a large natural-history study in which opioid-dependent polydrug users in opioid-agonist maintenance treatment carried electronic diaries for up to 16 weeks. Here, using some of the data from that study, we report that craving is greater in the combined presence of drug cues and stress than in the presence of either alone—but not for all users.
Materials and methods
Participants
The participants were methadone- or buprenorphine-maintained opioid-dependent polydrug users at a treatment-research clinic in Baltimore, MD. All were participating in a 46-week natural-history study of stress, geographical location, and drug use. Our prior publications of data from a subset of participants in this study focused primarily on ambulatory physiological monitoring (Hossain et al, 2014; Kennedy et al, 2015; Rahman et al, 2014) and an examination of the relationship between stress and drug use (Furnari et al, 2015).
During screening, participants completed the Addiction Severity Index (ASI; McLellan et al, 1985 and the Diagnostic Interview Schedule (DIS IV; Robins et al, 1995) and were given physical examinations and psychological testing. The main inclusion criteria were: age 18 to 75 years, physical dependence on opioids, and (due to the behavioral-geography focus of the parent study) residence in Baltimore City or one of the surrounding counties. The main exclusion criteria were: history of any DSM-IV psychotic disorder, bipolar disorder, or current Major Depressive Disorder; current dependence on alcohol or sedative-hypnotics; cognitive impairment precluding informed consent or valid self-report; conditions that preclude urine collection; or medical illness or medications that would compromise research participation. This study was reviewed and approved by the National Institutes of Health Addictions Institutional Review Board. Participants gave prior written informed consent and were paid for completing the research components of this study.
Procedure
Participants attended clinic 5 to 7 days a week; methadone or buprenorphine was administered daily, and individual counseling was given weekly. Urine was collected under observation and screened for illicit drugs thrice weekly.
After 2 weeks of treatment, each participant was trained to use a smartphone as an electronic diary (ED) and then carried it for up to 16 weeks, during weeks 3–18 of the study. The EDs were programmed with our electronic-diary software (Vahabzadeh et al, 2004). Participants received 3 random prompts (RPs) per day, timed to occur only during self-reported waking hours, which were programmed into the ED. Participants rated how much they craved opioids and cocaine, stress level, and a series of 28 mood adjectives. They also indicated whom they were with, what they were doing, and where they were from drop-down lists. Participants were asked if they had seen, been offered, or seen others using an opioid, cocaine, cannabis, methamphetamine, alcohol, or tobacco in the last 5 min or since they got to their present location. Participants made two additional types of entries not reported here: event-contingent entries, which they initiated whenever they felt ‘more stressed, overwhelmed, or anxious than usual’ or any time they used a drug for nonmedical purposes, and end-of-day entries. We analyzed RP ratings of craving rather than participant-initiated reports of actual drug use, because the craving ratings were the most proximal and sensitive readout of what we wanted to assess. Not all instances of craving result in drug use, especially for users who have decided to enroll in treatment. For those users, however, craving itself can be an aversive experience (Tiffany and Wray, 2012). Even instances of craving that are not strongly aversive are likely to be unwanted distractions during recovery. Therefore, we consider craving inherently worthy of clinical and scientific attention.
The participants were paid $10 each week for completing at least 82% of their random prompts, or were given a warning if they did not meet the criterion. If the participant did not meet the 82% completion criterion for 2 weeks after being warned, they were removed from the study and assisted with transfer into community-based addiction treatment.
Data Analysis
To create a predictor for drug-cue exposure, we coded participants’ responses as ‘1’ when they reported having seen or been offered opioids, cocaine, cannabis, methamphetamine, alcohol, or tobacco, and ‘0’ if not.
To check for collinearity between drug-cue exposure and our other momentary predictor (stress, rated 1–5), we examined the overall distribution of cells in a 2 × 5 table across all random-prompt entries. We also quantified the association, using a random-intercept, random-slopes model in SAS Proc Mixed in which cue exposure was the predictor and stress rating was the outcome. In this and all our other mixed models, we used an ‘autoregression+noise’ error structure (Schwartz and Stone, 2007), in which a spatial-power function accounts for the uneven intervals between entries.
To test our main hypotheses—that heroin and cocaine craving would be greater in the combined presence of stress and drug cues than in the presence of only one or neither (ie, that stress and cue effects would be at least additive)—we ran two models, one for heroin craving, one for cocaine craving. We constructed the models to distinguish person-level differences from within-person relationships, the latter being a stronger basis for conclusions about how changes in a predictor lead to changes in outcome. Mixed models can account for person-level differences when participants differ widely on the outcome variable, but do not automatically account for the possibility that people differ widely on predictors (van de Pol and Wright, 2009). We calculated person-level means for stress severity and drug-cue exposure (the latter was the ‘mean’ of each participant’s momentary 0’s and 1’s), and we used those means to create person-mean-centered versions of each of the momentary predictors. Each model thus contained the following six predictors: person-centered momentary stress rating, person-centered momentary cue exposure, and the interaction of the two momentary predictors; person-level mean stress, person level ‘mean’ cue exposure, and the interaction of the two person-level predictors. Type 3 tests for the first three predictors reflect within-person relationships across time, controlling for person-level differences. The Stress × Cue interaction term denotes additive effects if it is not different from 0, more-than-additive (ie, synergistic) effects if significantly greater than 0, and competitive effects if significantly less than 0.
For all models, we specified denominator degrees of freedom using the conservative method recommended by Bolger and Laurenceau (2013), reflecting the number of participants rather than the number of time points. Alpha was set at.05, two-tailed, for all analyses.
To show the degree of heterogeneity across participants, we plotted histograms of the model-derived Stress × Cue parameter estimates (empirical best linear unbiased predictors; EBLUPS) for all participants, and we noted descriptively how many participants showed patterns of results consistent with the group means (Branch, 2014). All analyses were performed using SAS, version 9.4 (SAS Institute, Cary, NC).
Results
Participants and EMA Reporting and Compliance
Data were collected between 14 July 2009 and 4 June 2015. Of 226 individuals who signed consent, 182 provided EMA data for at least 2 weeks, 12 provided EMA data for less than 2 weeks, and 32 left the study before providing any EMA data. The demographic and drug-use histories of the 182 participants whose data are reported are shown in Table 1. They provided EMA data for a mean (±SD) of 101.0 (±26.6) days (range 14–156) over 18,379 study days. On average, they completed 2.4 (±0.4) random-prompt entries per day for a total of 44,326 entries, with an overall compliance rate of 81%.
In event-contingent entries (not analyzed here), they made a total of 2763 drug-use reports and 1787 stress reports; 33 (18.1%) made no drug reports, and 24 (13.2%) made no stress reports. An event-contingent entry for drug use was made every 6.7 days (0.15 per day), and an event-contingent entry for stress was made every 10.3 days (0.10 stress reports per day).
In the 44,326 random-prompt entries, as stress ratings increased from 1 to 5, the corresponding percentages of drug-cue reports were 31%, 42%, 38%, 35%, and 41%. Thus, although drug-cue exposure did predict higher stress ratings in a random-effects model (least-squares means 1.61±.05 without drug cues, 1.70±0.05 with drug cues; F(1,178)=8.85, p=0.003), the two were not so strongly collinear as to preclude their simultaneous use as predictors of craving.
Stress × Cue Effects on Momentary Craving for Heroin
The output from this model is shown in Table 2, and the within-person Stress × Cue interaction (row 4 of the table) is graphed in Figure 1a. Controlling for between-person differences in mean stress ratings, frequency of drug-cue exposure, and their interaction, there were significant positive main effects of momentary stress and momentary drug-cue exposure. The interaction of the two appeared to be positive, as reflected in the steeper slope for the ‘Drug cue present’ in Figure 1a. This interaction was not statistically greater than 0 (F(1,178)=2.11, p=0.148), but the confidence interval (−0.007–0.044) was predominantly greater than 0. While not statistically significant, the interaction effect is in the direction that suggests a synergistic interaction and is of a magnitude that is nearly identical to the statistically significant corresponding effect in the model predicting cocaine craving (see below).
The tests for random effects in Table 2 show statistically significant between-person variability in heroin craving (at its intercept) and in the main and interactive effects of stress and cue exposure on heroin craving. This can be seen more clearly in Figure 2a, a histogram of the person-specific estimates for the Stress × Cue interaction. Slopes greater than 0 indicate exacerbation of the cue effects by stress (or vice versa); a slope of 0 indicates that the effects of the two predictors are no more than additive; slopes less than 0 indicate that cue exposure suppresses the effects of stress (or vice versa). In our sample, values tended to be either above 0 or very near it. (There was one exception, visible on the lower left of Figure 2a: a participant who reported heroin craving only on the 6/41 occasions when he was stressed in the absence of cues, not on the 20/45 occasions when he was stressed in the presence of cues.)
Cue × Stress Effects on Momentary Craving for Cocaine
The output from this model is shown in Table 3, and the within-person Stress × Cue interaction (row 4 of the table) is graphed in Figure 2a. Controlling for between-person differences in mean stress ratings, frequency of drug-cue exposure, and their interaction, there were significant positive main effects of momentary stress and momentary drug-cue exposure—along with a positive/synergistic interaction of the two, F(1,178)=4.39, p=0.038, denoting a more-than-additive effect of stress and cues on cocaine craving.
The tests for random effects in Table 3 show statistically significant between-person variability in cocaine craving (at its intercept) and in the main and interactive effects of stress and cues. Figure 2b shows person-specific slopes for the Stress × Cue interaction; they tended to be either above 0 or very near it.
Raw Mean Data at the Person Level
To check the ‘ground truth’ of our model-derived estimates, we examined raw person-level data, as suggested by Branch (2014). For simplicity, we assessed each participant’s mean craving for heroin and cocaine across four conditions: cues present, stress rating>1, both, and neither. By doing so, we were able to confirm that ‘exacerbating’ interactions of stress and cues were qualitatively observable in a large plurality of individual participants (43% of participants showed the ‘exacerbation’ pattern for heroin craving, 38% for cocaine craving). Those who did not show the exacerbation pattern had relatively flat ratings of craving across the four conditions, but not opposing patterns. ‘Exacerbators’ and ‘non-exacerbators’ showed similar ranges of craving scores and stress ratings. These findings (not shown) are implied by the results of the models.
Discussion
Craving is a key feature of addiction: it predicts treatment outcome (Higley et al, 2011; Tsui et al, 2014) and has been added as a criterion for diagnosis of substance-use disorders in DSM-5 (Murphy et al, 2014). Understanding the factors that influence craving could help improve treatment outcomes and relapse prevention.
In this study we investigated relationships among stress, cues, and craving in our opioid-dependent, polydrug-using patients. Although we cannot draw causal conclusions from our data, the ‘stress and craving ’ results replicate our earlier work (Preston and Epstein, 2011) and are consistent with a large body of research showing that craving and the likelihood of relapse are greater in the presence of stress (Breese et al, 2005; Law et al, 2016). The ‘cue and craving’ results are consistent with a parallel (though more mixed) body of research on cues (Papachristou et al, 2014; Shiffman et al, 2015; Witteman et al, 2015). The small but reliable association between stress and the presence of drug cues is consistent with findings in laboratory studies that drug-cue exposure is itself stressful to people who are trying to abstain from use (Sinha et al, 2006; Sinha et al, 2003).
Our main question was whether craving would be exacerbated (ie, increased at least additively, perhaps more) when stress and drug cues were present together. To our knowledge, the only prior EMA study to examine such a question systematically was a study of smokers, in whom the pattern seemed to be not one of exacerbation, but suppression or mutual dampening (Shiffman and Gwaltney, 2008). However, the predictor tested in that study was not stress per se; it was negative affect, which was operationalized to include low-arousal states such as ‘sad’ and ‘miserable.’ It seems plausible that cue exposure could have different effects during low-arousal negative affect than during the high-arousal, sometimes mixed-valence state (Folkman, 2008) that is stress.
Stress itself, however, has not reliably exacerbated the effects of drug cues on craving in human laboratory studies as it does in animal studies (Banna et al, 2010; Buffalari and See, 2009; Feltenstein et al, 2011). For example, Back et al (2015) exposed prescription-opioid abusers and controls to a stressor (the Trier Social Stress Task, TSST) and drug cues (an audio script, paraphernalia, and video); the stressor increased ratings of craving, and the cues increased ratings of craving, but there was no sign of synergism (ie, no statistical interaction) between the two. McRae-Clark et al (2011) conducted a similar study in marijuana-dependent participants: cues and the TSST each increased marijuana craving, but the combination did not increase it further. Ray et al (2013) exposed smokers to personalized stress-imagery scripts followed by smoking cues (holding and smelling an unlit cigarette); each increased craving compared to neutral conditions, but cues did not exacerbate stress-induced craving. Thomas et al (2011) presented dependent drinkers with the TSST and an alcohol cue (a beverage that they were asked to hold and sniff). In that study, stress did not increase craving, although the alcohol cue did increase craving (with or without stress).
The absence of exacerbatory interaction (or even an additive effect) of stress and cues in human laboratory studies could reflect suppression of one effect by the other—stress may have distracted people from cues and vice versa. It could also reflect ceiling effects on the amount of craving most people are likely to experience in a laboratory; Thomas et al (2011) note in their literature review that stress in a laboratory setting failed to induce craving for alcohol in about half of the relevant published studies. Further complications might include differences among drugs (stress-induced craving seems more reliable in people dependent on opioids or cocaine; Fox et al, 2008; Jobes et al, 2011; Schmidt et al, 2014; Sinha et al, 2006) and among users (for drinkers, individual differences in coping skills can modulate responses to different types of stressors and cues; Snelleman et al, 2014). One human laboratory study did show a combined effect of stress and drug cues (on cocaine craving). But that study used yohimbine as the stressor (Moran-Santa Maria et al, 2014), rather than the more typically used TSST. Yohimbine has been used as a ‘pharmacological stressor’ in rodent models of relapse (Banna et al, 2010; Buffalari and See, 2009; Feltenstein et al, 2011), but recent data have cast doubt on whether it truly acts as a stressor in rodents—for example, it does not produce conditioned place aversion, as do other stressors (Chen et al, 2015). In the Moran-Santa Maria et al, study, yohimbine did increase ratings of ‘anxiety’ in cocaine-dependent women (not in controls), but apparently did not increase ratings of ‘distress’ on the same questionnaire.
The main contribution of our EMA data is to show that stress and cue exposure can have at least an additive effect—and, for many users, more than additive—on cocaine craving, and possibly on heroin craving, in daily life.
Stress and cue do not appear to dampen each other’s effects, as might have been inferred from the available human-laboratory data—at least, not in the overwhelming majority of users. Because our analytic approach allowed us to document and quantify between-person heterogeneity, the current findings complement our prior finding that the effect of stress on actual drug use is also heterogeneous (Furnari et al, 2015).
We did not make direct comparisons between heroin and cocaine craving, partly because all our participants used opioids and only a subset used cocaine. However, the data in Figure 1 (and the parameter estimates) suggest that momentary stress had a stronger main effect on craving for heroin than for cocaine. This is consistent with a finding, from one of our earlier EMA studies, that event-contingent reports of cocaine use (compared to reports of heroin use) were associated with a greater likelihood of almost every daily-life activity we assessed (socializing, working, chores, shopping, watching TV) except one: being in an argument, which was associated with heroin use (Epstein et al, 2008). We speculate that heroin, more than cocaine, is wanted and used for its ability to soothe stress.
One limitation of our study is its observational design, along with the cross-sectional nature of each of our momentary assessments. These limitations preclude firm conclusions about causality. It seems very likely that craving could cause exposure to (or heightened awareness of) drug cues, and also that craving could cause stress. In future analyses, we may be able to draw additional conclusions by examining lagged associations. Another limitation is that our participants rarely reported very high levels of either craving or stress, and we cannot be certain that the low intensities reported here are clinically significant. In EMA data from a different but demographically similar group, we have shown that the mood changes, craving changes, and exposures our participants report in RP entries do predict actual drug use within the next few hours (Epstein et al, 2009; Preston and Epstein, 2011; Preston et al, 2009). That association was present despite the fact that our random prompts, in the earlier studies and this one, cover only the participant’s self-reported normal waking hours. Cue/stress/craving associations that occur very late at night are not detectable in our RP entries.
Despite these limitations, we have demonstrated that craving for opioids and cocaine is exacerbated in the simultaneous presence of drug cues and stress compared to the presence of either alone. The ambulatory nature of our assessments enabled us to detect relationships that have been elusive in controlled human-laboratory settings. These results are consistent with behavioral and neurobiological research on addiction and stress. An important next step is to examine sources of heterogeneity with idiographic analyses (Hekler et al, 2016) so treatment can be more effectively personalized.
