“Some new science demonstrates that marijuana may not have the harmful effects critics claim. In fact, while pot had no measured impact in a new study, the very legal and very lucratively-marketed substance alcohol actually has a worse health impact on young users. Specifically, a new study of substance-using teenagers’ brains shows that the regular use of alcohol had a harmful effect on the boozing group, while the toking-up group’s brains suffered little alteration.”
