Um... All those are legal. Also, the first and third have known beneficial medical effects which would still be allowed if my proposal is enacted.
Isn't that a despicable reason to demand somebody's death?
If the government mobilizes to kill millions of its citizens, how are you confident that the line will be drawn at the point you think is acceptable? (Why we should let you set the line is another debate, but luckily you aren't in a position of power.) Perhaps there's someone else like you, but who takes it a step farther and believes something you do and don't think is immoral should be a capital offense. Your wanting to kill pot smokers is no more crazy than me wanting to kill coffee drinkers.
But what kind of a pansy wants to do that?!
Where is rms when you need him?
The American Heart Association, however, recommends against starting to drink to be healthier. http://www.americanheart.org/presenter.jhtml?identifier=4422 While light alcohol consumption does have small benefits, you could make a much, much bigger difference in your overall health by exercising and following a healthy diet. One drink a day probably does have marginal benefits, but from a public health perspective I can see why organizations don't actually recommend it -- people in the aggregate would think it is more meaningful as a recommendation than it actually is and use it as an excuse to drink to excess.
One thing to keep your eye on is Sirtris Pharmaceuticals's (now a subsidiary of GSK) amped-up resveratrol (the good stuff in red wine) derivative. The idea is to get the benefit of drinking 1000 glasses of red wine a day without actually killing yourself. It will be approved for treating diabetes but will be of interest to absolutely everyone that can afford it. http://www.reuters.com/article/healthNews/idUSN0743693420080...

Seems to indicate that THC stops inflammation of blood vessels by suppressing the immune system's response. Also seems that oral delivery was used vs. smoking.
