The legality of Cannabis for general or recreational use varies from country to country. Possession of Cannabis is illegal in most countries as a result of the agreement on Indian Hemp in the International Opium Convention, 1925, and the UN Single Convention on Narcotic Drugs, 1961. However, many countries have decriminalised the possession of small quantities of Cannabis; see the full list at Wikipedia.
Some states in the US allow use of Medical Cannabis in State, Territorial, Indian Reservation, City, and Federal District Laws, although the use is illegal by Federal Law. Federal Agencies claim that Federal Law comes first.

The policies of ALL the Member States of the European Union (with the exception of the Netherlands and Spain) on the availability of Cannabis for medical use is incompatible with Society's Rule of Law in general, and the European Convention on Human Rights in particular.
Cannabis is available for recreational use from Dutch 'Coffeeshops' for persons over 18 years of age.
The Netherlands has not fully legalised Cannabis, but decriminalised it by not enforcing its own laws.
As this policy it now about 40 years old, it can only be viewed as a de facto legalization of Cannabis.
Charitable Cannabis Clubs have been founded in Spain, whose lawfulness has been confirmed by courts in Catalonia
and in the Basque region. People join together to grow Cannabis and distribute it to members of the club at cost price.
Cannabis remains a Schedule I Substance under Federal Law as of 2015.
Some Cities and Indian Reservations have legalization policies separate from their surrounding States.
