Abstract
THIS paper reports the results of qualitative and quantitative analysis of 36 reefers or ‘pro-reefers’ (samples of herbal or resin cannabis sufficient for one reefer) produced in London and Leeds. As far as we know it is the first time reefers in actual use have been so analysed. The reefers were obtained from three different groups: group A, regular smokers in the London area, some of whom had asked for psychiatric help; group B, regular users in Leeds, none of whom had sought medical advice about their cannabis smoking; group C, casual users in the London area. The results show a very wide variation in potency and indicate that more than half were below the threshold dose.
