Compared with other recreational drugs – including alcohol – marijuana may be even safer than previously thought. And researchers may be systematically underestimating risks associated with alcohol use. Those are the top-line findings of recent research published in the Journal Scientific Reports, a subsidiary of Nature. Researchers sought to quantify the risk of death associated with the use of a variety of commonly used substances. They found that at the level of individual use, alcohol was the deadliest substance, followed by heroin and cocaine. Marijuana was all the way at the bottom of the list – roughly 114 times less deadly than booze, according to the authors, who ran calculations that compared lethal doses of a given substance with the amount that a typical person uses. Marijuana is also the only drug studied that posed a low mortality risk to its users. However, those involved with the study say it’s important to note that “safer than alcohol” doesn’t mean completely safe. There are any number of risks associated with marijuana use. Most of these risks involve mental health issues, and most increase the earlier you start using and the more frequently you use. You can see the study in full by clicking here.
