@indoc I believe the issue is the addictive nature. Once you try Pot or any addictive item for that matter, you will try it out for a second time. It is very easy to get addicted to something. Few people may be able to control and not increase their daily quota of the substance, however there are people who get heavily addicted. If the individual is responsible, it may be fine... but then these things rarely have any health benefits.. so if possible, why start in the first place.
