I agree. That being said, Gavajabra is still wrong.
One joint does not equal four cigarettes. Maybe one. Stop touting this because it's an outdated, bullshit fact. Not that it matters given the slant of my argument below.
The government won't support weed because it's too controversial because society is trained to think everyone who smokes is a burnout dumbass. Not that everyone thinks that, but enough do (including the ridiculous numbers of Christians politicians spend fucktons of money campaigning to) that they can't support it without risking their careers.
Secondly, there are plenty of legal things I can do that put my life and the life of others in immediate and critical danger if I'm a dumbass about it. Skiing. Drinking. As it turns out, those things can also cause permanent damage too! Liver problems, addiction, death, serious longterm injury, violence... am I missing anything?
Now, skiing and drinking, those are some things I can do for fun, right? And they have risks associated with them that I take responsibility for when I do them. Why isn't it legal for me to accept the risks of marijuana if its something I enjoy enough to consider those risks outweighed?
You say the government won't do it because one smoking session impairs you while one beer doesn't? I have a high enough tolerance that one smoking session with friends will not make me high by the time I want to drive (usually a half hour tops). Oh, wait, what about those people with low tolerances? Oh, yeah, what about those people with low tolerance for alcohol, like this obnoxious bitch I know who gets hammered after two, three beers? She feels it after one. Driving a little high is no more dangerous than driving a little drunk, in fact, much less dangerous. Driving stoned is fucking stupid, but then again so is driving plastered. What the fuck is the difference?
I rest my case.
