In its 2022 annual report, the International Narcotics Control Board:

• notes that the 1961 Single Convention on Narcotic Drugs classified cannabis as highly addictive and liable to abuse, and that any non-medical or non-scientific use of cannabis contravenes the Convention;
• expresses concern that this trend among a small number of governments is leading to higher consumption, negative health effects and psychotic disorders;
• notes with concern that the growing cannabis industry advertises products, particularly to young people, in ways that lower the perception of risk involved in using them;
• finds the impact of legalizing cannabis on society difficult to measure because legislative models vary from country to country and data is still limited;
• voices concern that many countries continue to have difficulties procuring enough controlled substances for medical treatment, including during emergency situations;
• highlights that countries are confiscating a high number of non-scheduled chemicals and designer precursors used in illicit drug manufacture and is concerned about the global spread of these substances.
