Some disagree with that statement.
Myth: No one has ever died from using marijuana
The Kaiser study also found that daily pot users have a 30% higher risk of injuries, presumably from accidents. These figures are significant,
though not as high as comparable risks for heavy drinkers or tobacco addicts. That pot can cause accidents is scarcely surprising, since marijuana has been shown to degrade short-term memory, concentration, judgment, and coordination at complex tasks including driving.(1) There have been numerous reports of pot-related accidents --- some of them fatal belying the attractive myth that no one has ever died from marijuana., One survey of 1023 emergency room trauma patients in Baltimore found that fully 34.7% were under the influence of marijuana, more even than alcohol (33.5%); half of these (16.5%) used both pot and alcohol in combination.(2) This is perhaps the most troublesome research ever reported about marijuana; as we shall see, other accident studies have generally found
pot to be less dangerous than alcohol. Nonetheless, it is important to be informed on all sides of the issue. Pot smokers should be aware that accidents are the number one hazard of moderate pot use. In addition, of course, the psychoactive effects of cannabis can have many other adverse effects on performance, school work, and productivity.
