Legal marijuana: Confusion in Colorado over cannabis tax

8 May 2013 Last updated at 00:38 BST

Marijuana has been legal for medicinal use in Colorado for more than a decade. In November, voters in the state approved the recreational use of the drug as well.

Supporters of legalisation claimed it would raise much-needed tax revenue. However, lawmakers have so far failed to reach a deal to tax and regulate the industry.

The BBC spoke to people on both sides of the debate in Colorado about the confusion over what happens now that marijuana is legal.
