Same with people who drink. I find drunk people pretty loud, obnoxious and annoying. Or, on the other hand... they could be depressed or violent. That's always fun too.
And the smell...
I find that I am not a fan of alcohol. I don't have the stomach for it and as I just said, I find most drunk people very annoying. I think alcohol is dangerous, as well... Trust me, I've had fun with it and I love a beer now and then, but human beings abuse it.
On the other hand, at least for me, pot does little more than what Doug said in the movie... it makes things a little fun! It doesn't turn me into a different person as I've seen alcohol do on more than one occasion to many different people.
Yes, a goofy, immature stoner that you can pick out from a mile away is probably just as annoying as someone who is drunk.
I smoke every day, hold a good job with a lot of responsibility, talk about pot casually and without paranoia, and I believe very strongly that it should be legal. Most people don't know that I smoke unless I tell them... which I usually do because I'm not ashamed of it. It's not a religion, but maybe if more people spoke up that they smoked, the mass populace would realize that people are smoking this stuff and it's less harmful than alcohol.
And just like I can't drink, I realize there are people out there who can't really smoke because it makes them paranoid or whatever. But at least if they wanted to go have a drink, they can do so without being penalized for it.
Bunch of garbage. This whole thing being illegal and alcohol being eeeeverywhere. I've thought so since before I even smoked the stuff.
PS. Not everyone sounds like an idiot when they're high. Some can actually hold decent conversations and keep their shit together.
