"In humans, marijuana use is associated with increased heart rate and postural fluctuations in blood pressure, which may be implicated in developing heart attacks or strokes.11 Multiple case reports of acute coronary syndrome after marijuana use have been published in the literature. More recently, a study in the Journal of the American Heart Association reported that there are potential cardiovascular dangers to young adults using marijuana.12 One study found an elevated risk up to 4.8 times higher for myocardial infarction (MI) within 1 hour of smoking marijuana.13 In patients with a history of MI, marijuana use more than once a week was associated with a 3-fold increase in mortality."
"Here's what they found: Most of the participants never used cannabis and they were never reported to have violent behavior. 38% of the participants did try cannabis at least once in their life. Most of them experimented with cannabis in their teens, but then stopped using it. However, 20% of the boys who started using pot by age 18 continued to use it through middle age (32-48 years). One fifth of those who were pot smokers (22%) reported violent behavior that began after beginning to use cannabis, whereas only 0.3% reported violence before using weed. Continued use of cannabis over the life-time of the study was the strongest predictor of violent convictions, even when the other factors that contribute to violent behavior were considered in the statistical analysis. In conclusion, the results show that continued cannabis use is associated with a 7-fold greater odds for subsequent commission of violent crimes. This level of risk is similar to the increased risk of lung cancer from smoking cigarettes over a similar duration (40 years). The authors suggest that impairments in neurological circuits controlling behavior may underlie impulsive, violent behavior, as a result of cannabis altering the normal neural functioning in the ventrolateral prefrontal cortex."
14.6% of marijuana users committed violent crimes, in comparison to 2.7% of non drug users, or were 5.4 times more likely. And inb4 cultural reasons, it's consistent in other countries, for those in higher economic statuses, and it's not true that other illegal drugs necessarily lead to acts of violence, like with LSD or mushrooms. So no, it is specific to marijuana, the fact it's illegal, and not just a really strange coincidence.
