On Wednesday 2 December 2020, the United Nations Commission on Narcotic Drugs voted to remove cannabis from Schedule IV of the 1961 Single Convention on Narcotic Drugs. In rescheduling, the UN has recognised that cannabis carries fewer risks than other Schedule IV drugs such as heroin. The change also signals that the UN now accepts that cannabis can have medical benefits. Currently, more than 50 countries have legal forms of medical cannabis. The change in scheduling is expected to make it easier to conduct research into medical cannabis.
