Just because something is illegal per the law does not make it wrong, merely unlawful.
Conversely, making something legal, that we all know is inherently wrong, will not make it right, either.
The effects of marijuana are widely known. I don't think anyone here will debate the fact that it is a debilitating drug. The fact that alcohol is a debilitating drug and is legal does not mean we should make legal every mind-warping drug that is out there in the interest of free commerce and tax revenue. Piss on the tax revenue. Don't we pay enough taxes as it is? Don't we have enough people hooked on drugs, making people's lives miserable, making a nuisance of themselves on the roads and out in society, than to make it easy to get, legal to do in public? The only reason some people don't do it is because it is illegal. I know that for a fact. The number of users would double.
And where will it stop? Make cocaine legal next? And then what? Methamphetamine? Prescription pain killers?
No, this reminds me of where TV was 50 years ago versus where it is now, due to an increasingly decadent society that convinces someone that it isn't really wrong. I can't watch a show with my 13 year old but that foul talk, that used to be reserved for rated R movies, is flying out of someones mouth. Before you know it it'll be kosher for your pastor to use the Fword to punctuate his sermons on Sunday.
This debate is the result of a decadent nation, on the decline, who want others to jump on the band wagon and agree with them that "Oh you're right, it's not so bad!". "Ah com'on, the Fword isn't that bad, we should be able to use it during regular day time hours on our networks." "Marijuana is a much milder drug than alcohol, which is already legal!"
Bla bla bla.
