Marijuana and some so-called “club drugs,” such as ecstasy, may soon be legalized in the United Kingdom. Deputy Prime Minister Nick Clegg has ordered a review of current UK policies following an investigation into Britain’s war on drugs.

Liberal Democrats say the British government is losing the war, and are proposing a reform that could be partly modeled on recent legalization of recreational pot in Colorado and Washington State. They also point to New Zealand’s recent experimentation with licensing designer drugs if the manufacturer can prove the drugs are safe for the user.

The review, due to be published before Christmas, is also expected to prescribe “shooting galleries” for heroin users in an attempt to reduce crime. The report may ruffle some feathers in parliament – conservative home secretary Theresa May is unlikely to support any changes to current UK drug laws.
