Alaska to legalise the recreational use of marijuana
Alaska has become the third state in the US to legalise the recreational use of marijuana.
A ballot measure approved by Alaskan voters in November kicks in today, allowing adults 21 years and older to possess up to an ounce of marijuana and up to six plants.
Regulations for the sale of the drug still need to be hammered out.
Smoking marijuana in public remains off-limits, and police officers in Alaska's largest city plan to strictly enforce the public ban.
