You may have read this week that a new "20-year research study" on marijuana use "finally demolishes claims that smoking marijuana is harmless," and has found that it "makes you stupid," that "smoking marijuana over the long-term can develop cancer" [SIC], and that marijuana is "as addictive as heroin." At least, that's what you'd conclude if you'd read most media coverage of the study. But if you'd actually read the study yourself, you'd likely walk away with very different conclusions.
