I think marijuana should be legalised for medical and recreational purposes. This is because it is essential for medical purposes to help people with an illness such as SLA. Legalising marijuana means reducing criminality and it should be managed as cigarettes.
Moreover, recreational marijuana should be used by people over the age of 18 and in any place. In addition, there is no scientific proof that marijuana is harmful, unlike cigarettes and alcohol. Therefore, just like cigarettes and alcohol, there shouldn't be a limit regarding the quantity allowed.
