Recreational marijuana – which was legalized in Washington, D.C. and decriminalized in February 2015 in Alaska – has been deemed to be less dangerous as compared to both tobacco and alcohol according to several scientists.
Scientists have argued over the years about the safety of cannabis in comparison to alcohol – however in a report published in January 2015 in Scientific Reports researchers measured the potential harm caused by each of these drugs in a more quantitative manner – by comparing a lethal dose with how much of the substance is typically consumed socially.
The report found that the dangers of marijuana ‘may have been overestimated in the past’ while the risk of alcohol has been ‘commonly underestimated’ according to the researchers.
The report compared the potential of death from the typical and recreational use of 10 drugs: marijuana – alcohol – tobacco – heroin – cocaine – ecstasy – methamphetamine – diazepam – amphetamine and methadone.
According to the findings cannabis was found to be safest among the drugs and also when specifically compared to cigarettes and alcohol.
