Weed needles will fuck up your life. Don't get into it.
I agree that Alcohol is worse than Weed. I think it would be Ok to have Weed legalized, as long as it was handled properly by the government like they do with cigarretes and alcohol. It would probably help the economy, and you wouldn't have to waste the cops time hunting down a couple of stoners who just like to sit in their basement and smoke weed. lol.
Personally I don't care...
but if it was legal:
Economy may change, have illegal immigrants growing that shit everywhere
Kids may not smoke it, because it is now legal, so doing legal things is so uncool
Look at Amsterdam (everyone wants to go there, why... because of marijuana, and other things too...)
Life is... Good!
I don't see alcohol as being more dangerous to ones self as weed. Just think, having two pints a day won't really have any long term effects on your liver, your liver will be able to push out the toxins. Lets go into really long term now, you've been drinking 2 pints a day for around 25/30 years. Imagine having 2 spliffs a day for that amount of time, you'll be fucked in the head, I can't even imagine how paranoid someone would be...
Though, weed does have medical attributes which can be counted as useful. I sort of agree with Spritwind here, if someone we could control the flow of weed to people then maybe, but within this day and age I think it would be impossible.
