The heavy cannabis users were also skinnier on average and skinnier people have lighter bones. Hip fracture risk goes down, as your weight goes up, nearly half of underweight. Women have osteoporosis but less than one percent of obese women do which makes total sense being obese, forces your body to make your bones stronger to carry around all that extra weight. That's why weight-bearing exercise is so important. Portent to constantly put stress in your skeleton. It's use it or lose it. That's why astronauts can lose a percent of their bone mass every month. Their bodies aren't stupid. Why waste all that energy, making a strong skeleton. If you're not going to put any weight on it. So, maybe that's the only reason heavy cannabis users have frailer bones because they tend to be about 15 pounds lighter. Wait a second, users are Slimmer. What about the munchies? The lower BMI of heavy. Cannabis users may seem counterintuitive, given the appetite stimulation, but this isn't the first time this has been noted and pop-culture depicts marijuana users as a sluggish lethargic unproductive. Juror of compulsive snackers and it's true that marijuana has been found to increase food intake. A single hit can increase appetite and so you'd expect obesity rates to rise in states that legalized it. But if anything, the rise in obesity appeared to slow after medical marijuana laws were passed where it appeared to just keep rising in other states. The reason pot smokers may be Slimmer is because the effect of smoke marijuana on metabolism. We've known for nearly 40 years, that within 15 minutes of lighting up, your metabolic rate goes up by about 25% and stays there for at least an hour. So that may be playing a role. So, is that why heavy cannabis use is associated with lower bone, mineral density and increased risk of fractures? They're just not as overweight. No. Even taking BMI into account heavy cannabis, use appears to be an independent predictor of weaker bones.
