As far as one half of the most famous pot smoking duo of all time is concerned, the medicinal properties of marijuana go way further than medical science currently suggests. He has of course been an active and outspoken marijuana smoker for most of his life, but it was after he announced that he was diagnosed with prostate cancer in 2012 that he began using hemp oil. Incredibly, it wasn’t long – in fact it was only a month later – when he once again spoke publicly to state that he was now 99% cancer free. And as far as he was concerned, this came entirely down to natural remedies including hemp oil.

“Did I mention I am 99% cancer free? Thanks to my “medication”. Hemp oil works but you have to believe…..I believe….tc” — Tommy Chong
