Once more, I just do not understand why anyone needs to alter their mind, for pleasure, with any drug, legal or illegal... The societal costs are just too high to allow use of illegal drugs. All legal and illegal psychoactive drugs (any substances that affect mood, perception and thought) can have harmful effects if abused, but the detrimental results of allowing use of any of the current illegal drugs, including marijuana, is too great a risk to take.

You can't define "bad" substances by their state of legality or not.

We had better ban chocolate and sugar, because it might make someone happy. I could make a far stronger arguement for the ill effects of sugar on society than pot.

Sugar, potatoes and other starchy foods stimulate a seratonin response in the body -- seratonin is a "happy hormone" mimicked by most anti-depressive medications. Oh my, they'll have to go, too.

Oxygen bottles? Gone! They can make you energetic and high.

Get rid of all those highlighters and every adhesive, because someone might sniff it.

Herbs, spices and seasonings -- all gone. All produce medicinal effects to some degree, therefore they have dangerous side effects and should be banned from use in food.

Gambling produces an excited hormonal response in the brain, as does all manner of sports. Skiing, football, rock climbing, bungee jumping... all gotta go.

Working out with weights -- gotta go. Affects the hormones. So does running and other prolonged physical activity.

TV programs will have to be carefully monitored not to show anything that might alter a persons mood. No tear jerker chick flicks, no adreneline pumping action films.

If we made all of the above illegal for the same reasons pot is illegal, would you then argue that because they were illegal they were too dangerous?
