While the United States Drug Enforcement Administration (D.E.A.) mulls over the legal status of marijuana, here is a global picture of where other societies and governments stand (including each U.S. state).
It is interesting to note that only three countries fully legalize cannabis usage for any reason: the Netherlands (to the surprise of nobody), Uruguay, and — of all places — Bangladesh.
Several other countries otherwise not known for being especially progressive on such issues — such as Argentina, Brazil, Colombia, Iran, Mexico, the Philippines, and Russia — take a liberal stance on marijuana. Conversely, famously progressive places such as Australia, Canada, New Zealand, and Scandinavia take a stricter view on marijuana use.
Then there are those nations in limbo, which, in practice, if not in law usually allow for cannabis to be used recreationally as well as medicinally. Ranging from Canada to India, enforcement of marijuana prohibitions can be arbitrary depending on where you live or on the whim of local officials.
