Have you noticed that your chest isn’t as tight as it used to be…or after smoking heavily your chest and the area around your nipples gets a little tender?
One of the potential side effects of smoking weed is called Gynecomastia also known in the locker room as ‘Man Boobs’.
Why Do Some Weed Smokers Get Gynecomastia?

Chronic and heavy marijuana use changes the hormones in your body and decreases testosterone. Testosterone is responsible for many of the things that make a man manly, like a deep voice, facial hair, muscularity and a flat chest.
Smoking Weed doesn’t just decrease testosterone, it alters the balance of hormones in your body. Less testosterone means more estrogen….and estrogen is what causes the growth of breast tissue and fat in men.
Although the illegality of marijuana has made studies difficult, the National Institute of Health listed marijuana as one of the causes of Man Boobs.
For a lot of guys, it’s tough to deal with and talk about, it keeps them from taking their shirt off on the beach, wearing tight shirts, and feeling comfortable in their bodies.
Is Man Boobs from Weed Reversible?
It’s possible that if you have just started to see them of feel tenderness that if you stop, the gynecomastia will go away on its own…but in order to do that you need to quit smoking weed completely AND you need to see your doctor to be sure that something else isn’t causing the issue.
Gynecomastia caused by puberty is pretty common and tends to go away on it’s own, but long term changes to your hormone profile may cause moobs that don’t go away when you stop smoking weed.
Keep in mind, it’s not just the smoke, but ingesting weed in any form: edibles, vaping etc may decrease testosterone and alter your hormonal balance.
