Can Smoking Marijuana Cause Enlarged Breasts In Men?

moobsThe next drug-related hysteria? Via CNN, a plastic surgeon claims that his field’s experts link pot smoking with gynecomastia, or, as the professionals term it, man boobs:

For now, if you have moobs, it’s probably best to put out that joint. Gynecomastia, otherwise known as man boobs (or moobs for short), is a condition that affects approximately 33% to 41% of men between the ages of 25 and 45.

Gynecomastia is caused by a hormone imbalance between testosterone and estrogen. Animal studies have shown that exposure to the active ingredient in marijuana can result in a decrease in testosterone levels, a reduction of testicular size, and abnormalities in the form and function of sperm.

So can smoking pot really give you man boobs? Probably. Although the association between marijuana and gynecomastia hasn’t been conclusively proven, it appears very plausible. The majority of plastic surgeons I’ve consulted with routinely inquire with their gynecomastia patients about cannabis use and recommend they stop smoking immediately.

    What a joke article. More like, when was the last time you did some pushups? and put down the bag of GMO chips.

    If it only gave me a vagina, too….fuck it…i’d never leave the house.

    this rumor is SO OLD – my 8th grade teacher used to tell us this back in 1989 to scare kids away from the “wacky tabacky”… as i’m fairly certain he had since the 1960s…

    sure as shit CNN would report this…

    I’m a little skeptical, too. I know a lot of very tough, in-shape dudes who are regular smokers.

      If you smoke before, you may get exhausted earlier, but you can reach your target HR more quickly. That’s especially helpful for those in good cardio condition already.
      If you smoke after, it “works” better. A good incentive for stoners to get moving.
      If you want to stop smoking, exercise reduces the urge and the withdrawal-induced insomnia.
      In short, whatever path you choose, cannabis use is no excuse for man boobs.

    Gynecomastia is caused by a hormone imbalance between testosterone and estrogen.

    Well, that certainly isn’t caused by factory-farm meat, which is loaded with artificial hormones (amongst other things).

      The condition is far more likely to develop with alcohol induced liver cirrhosis.

        That and this thing called “adipose tissue,” or fat.

    Here’s a piece that suggests that cannabis encreases testosterone.

    if I had to choose between having tits and giving up smoking… I think I would invest in a bra.

    This is exactly why you don’t get news from places named disinformation…or cnn for that matter. It’s also why you don’t take health advice from people whose solution to wrinkles is to cut off skin and their solution to weight gain is to suck fat out with a vacuum.

      If I have a personal agenda, it is the legalization of cannabis across the board and recognition of its numerous health benefits and the acknowledgment of the right of consenting adults to do what they want with their bodies. However, I try very hard to not let my personal beliefs influence the content on the site. That being said, you might notice that I’ve done several interviews in which I’ve mentioned my pro-legalization stance. You might also enjoy the interviews I’ve done with Adam Scorgie for similar reasons.

    A common scare tactic, amongst others. Thanks for the laugh.

    I also call bullshit; I’ve been smoking weed since I was fifteen, and my pot use has never directly impacted my weight or physical fitness. You know what does? Eating shitty food because you’re high. I think these folks have correlation and causation confused.

    “the active ingredient in marijuana can result in…abnormalities in the form and function of sperm.” I can personally attest that this is definitely not the case. And this is all the opinion of a plastic surgeon? Like anyone should ever trust a person whose job depends on convincing you that you need their services because you’re not attractive enough.

    This is such shit reporting. I mean look at the fucking percentage of men that experience this problem

    “Gynecomastia, otherwise
    known as man boobs (or moobs for short), is a condition that affects
    approximately 33% to 41% of men between the ages of 25 and 45. It’s even more common during puberty, affecting 60% of 14-year-old boys. Interestingly, it also affects 55% to 60% of men aged 50 and older.”

    added to the fact that “most cases of gynecomastia resolve spontaneously within a few months to a few years” I would conclude that maybe this is just a natural process that lots of men go through for various reasons. Guess what, bodies change, deal with it.

    The real question is why is something that is so common stigmatized to the point that 23,000 men underwent elective surgery to correct it in 2012 alone. Probably because people like this fucking plastic surgeon tell them that it needs to be corrected, that something is “wrong” with them. Seems like an uphill battle against nature. Notice that at no point he claims instances of Gynecomastia has risen, only that the number of surgeries has gone up. As in, more men feel that there is a need to “correct” their bodies, that doesn’t prove anything other than how obssesed our culture is with appearance.
