Megan Fox has openly admitted to smoking cannabis and called for the drug to be legalised.

In an interview with GQ magazine, the actress said the American government's anti-drugs stance was “all propaganda”.

"I can't tell you how much bullsh*t I've been through because I will openly say that I smoke weed," she said.

"People look at it like it's this crazy, hippy, f*cked-up thing to do. And it's not. I hope they legalise it."

The Transformers star, who recently admitted to being a bisexual,  added that she "would be the first in line to buy a pack of joints" if the drug was legalised.

Fox's comments about drugs are the latest in a series of unexpected revelations from the actress.

In May, Fox said there was “no question in my mind” that she was a bisexual.
