Minors and the legality of cannabis
Minors and the legality of cannabis is one of the issues around the legalisation of cannabis, with most jurisdictions placing strict age limits in a similar way as is done with the drinking age for alcohol. The details differ: in Germany, Luxembourg, Malta, South Africa and Uruguay, possession, consumption and cultivation of cannabis is legal for those that are at least 18 years old.
