An increasing number of countries have legalized medical cannabis. There is a broad range in the accessibility of medical cannabis markets in terms of the medical conditions eligible for authorization, the types of cannabis products that can be accessed, and the retail structure for receiving medical cannabis.
There is a need for evidence to understand how medical cannabis policies are meeting the needs of individuals authorized for medical use, and the broader impact on cannabis use and attitudes. For example, how do patterns of medical cannabis use differ from non-medical ‘recreational’ use? How are public perceptions and support for medical cannabis changing in society?
