This article examines the subjective impact of medical cannabis on the use of both licit and illicit substances via self-report from 404 medical cannabis patients recruited from four dispensaries in British Columbia, Canada. The aim of this study is to examine a phenomenon called substitution effect, in which the use of one product or substance is influenced by the use or availability of another.
In the city of São Paulo, the culture of crack use has undergone considerable changes over these 11 years since it was first described. The sociodemographic profile of the users is practically the same and most use is still compulsive, with significant physical, moral and social impairment among them. Sole use of crack has overwhelmingly been replaced by associations between crack and other drugs, thus characterizing users in the city of São Paulo as multiple drug users.
An ethnographic study of women and drug use in inner city neighborhoods in Kingston, Jamaica, revealed that cannabis is commonly used in conjunction with crack cocaine to minimize the undesirable effects of crack pipe smoking, specifically paranoia and weight loss.
