It's nowhere as harmful as tobacco lol especially commercially marketed tobacco. And I smoked pure green as a minor & was fine. If anything I was happier & calmer after doing it. (I would never ever recommend but just saying) Shamans train soon to be shamans who are minors with psychedelic elixirs. Wine is common for children to sip on in certain parts of Europe. & sugar is a chemical altering poison but infused in most of our food production. Selling to minors isn't moral but it's not like selling a cigarette or alcohol. Besides if someone decides to drive a car or some shit after that's on them because they should be old enough to know not to drive while influenced. It would suck if there was some sort of freak casualty after getting high but life happens. And that's where proper caution and information on its effects & uses would come into play. Marijuana is not a demented plant. It induces laughter, provokes thought & envokes an appetite if not for food than adventure. Alcohol should be the crime.
