Stoner dudes with tits might want to take a breather from smoking pot. According to experts, marijuana could be causing a hormonal imbalance leading to excessive breast tissue. Total buzzkill.
Man boobs, or gynecomastia, is the result of an abnormal development of mammary glands, due to a hormonal imbalance that "tips in favor of estrogen." It's apparently a growing problem, with the number of men getting surgery to correct the condition spiking by 30% between 2011 and 2012.
Animal studies have shown a link between the active ingredient in marijuana and a decrease in testosterone levels. However, studies on humans have been limited and inconsistent. But plastic surgeons are now advising gynecomastia patients to quit smoking pot.
According to one doctor on CNN.com, looking into the issue is reason enough to legalize it.
The legalization of marijuana in some state could make it easier for researchers to determine the exact effects of cannabis use on hormone levels, gynecomastia and other bodily functions. If a true link between smoking pot and gynecomastia does exist, then we should expect to see a spike in gynecomastia treatments in those states which have legalized marijuana.
