Joseph Gordon-Levitt has argued that cannabis use is "overly demonised" by society.
The 34-year-old actor has been open about smoking cannabis in the past and now argues it shouldn't be stigmatised. Although he isn't encouraging others to follow in his footsteps, the star wants people to make an informed decision.
"Even though the tide is turning, I think marijuana is overly demonised in our culture," he told Playboy magazine.
"I do know people who let it get out of control and let it play a part in their lives that's not beneficial. There's definitely an addictive quality, but it's psychological. It's not physically addictive in the way cigarettes or alcohol are physically addictive."
Joseph claims cannabis has played a major role for him professionally speaking, as it has improved his creativity.
"When I smoke weed I'm more liable to make connections I wouldn't otherwise make," he claimed. "Sometimes those connections are ludicrous, but sometimes they're great. You're like, 'Oh shit, I might not have thought of that,' and it actually makes sense in the morning."
The actor never smokes while he is making movies, explaining insurance means that is illegal on set. However, he has partaken when in the company of fellow industry stars.
When Joseph was making his upcoming flick Snowden, he smoked with director Oliver Stone on several occasions.
"With Oliver it was really nice because most of the time we were in this kind of high-stakes situation of working, and when we were smoking, we just smoked and watched a couple of movies a few times," he explained.
Joseph also touched on his use of other substances, specifically acid. He called it much more "intense" than cannabis and attempted to explain what the experience was like.
"I remember having a vivid bird's-eye view of where I was. Somehow, my vision went up above me, and not only could I see… It wasn't so much about myself. It was seeing a totality of how everything is all part of one thing, connected," he said.
