Marijuana use is becoming more and more common – a number of US states now permit recreational and medical use of marijuana. Others have decriminalized possession of small amounts. However, all these measures are on a state level and have no effect on federal law, meaning that marijuana is still prohibited on US territory. Recreational use of marijuana is legal in Alaska, Colorado, Washington D.C., Oregon and Washington. Many states have fully legalized marijuana for medical use. Marijuana users are not arrested and/or detained for possession. Canada, Israel and a lot of European countries have enacted similar policies.
