Be on the lookout in Portland for more man-boobs now that pot has been legalized. At least that is the claim of a plastic surgeon in the US..

If you’d like to challenge that, his name is Dr Anthony Youn, from YOUN Plastic Surgery, in Detroit, and this is what he professes to be the smoking pot rub…the doc says cannabis could lower testosterone levels in men.

Science has shown that ‘man boobs’ are caused by an imbalance in the body’s levels of testosterone and oestrogen. And smoking the weed can cause the balance to swing to the estrogen side. He added, ‘moobs’ – or gynaecomastia – can affect about 33 to 41 per cent of men aged 25 to 44.

Not so uncommon in guys removal of extra breast tissue has become the fifth most common plastic surgery choice for men in the U.S.

So if you check in for moob surgery don’t be surprised if they ask how much weed you been smokin’
