This study ensued from clinical observations based on spontaneous accounts by crack abusers undergoing their first psychiatric assessment, where they reported using cannabis in an attempt to ease their own withdrawal symptoms.
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 Sole use of crack has overwhelmingly been replaced by associations between crack and other drugs, thus characterizing users in the city of São Paulo as multiple drug users.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.
There is a growing body of evidence to support the use of medical cannabis as an adjunct to or substitute for prescription opiates in the treatment of chronic pain. When used in conjunction with opiates, cannabinoids lead to a greater cumulative relief of pain, resulting in a reduction in the use of opiates (and associated side-effects) by patients in a clinical setting. Additionally, cannabinoids can prevent the development of tolerance to and withdrawal from opiates, and can even rekindle opiate analgesia after a prior dosage has become ineffective.

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.
