I smoke while i play MK sometimes. I get emerged into it a lot more, and the same goes with anything else when I'm high. It stops me getting frustrated sometimes which helps too, but on the other hand it messes with my reactions a bit. I also find single player games really enjoyable after a smoke, unless it's a game like Dead Space lol. As someone else mentioned in the thread I seem to play better after a couple of beers too. I put that down to being in a more confident state of mind. After quite a few I play terrible though as I'm sure most people would.
I find most, not all people who are really against weed are the people who have never smoked it, or had a bad experience when they first started smoking it such as panicking, or smoked after drinking a lot. I also find it funny when someone calls someone who smokes weed a junkie (or words to that effect), while they drink every night and smoke untold amount of cigerettes lol. When I smoke weed I don't forget the whole of last night. I don't wake up feeling like s***. I've done less damage to my body. Laughed more (which is good for the soul lol). Spent less money. I could go on forever...
I have never seen someone get violent when stoned, or have never been violent when stoned. I have never seen someone, or been really ill from weed either. I have only had about 1-2 weird panics out of about 8-9 years when I first started which was all in my head anyway. I don't smoke chronically (I used to when I first started) because I enjoy it more when I do it in moderation. However, it's a different story when I've been out with people drinking. I can't explain how many times my friends have fallen out, done stupid things which they would never do. Get in fights. Make themselves very ill. Basically become completely different people. I actually hate some of my best friends when they've had a drink sometimes. However I've never really felt that way when they have had a smoke. When you've had a smoke you are still there if you understand what I mean. I love a beer as much as the next person, and I'm only comparing to alcohol because it's legal. I would much rather would walk past a group of stoners in the street than a group of drunk people any day. People think more when they are stoned compared to when they are drunk, and I think if weed was swapped with alcohol the world would be a better place.
Not trying to downgrade anyone who drinks and doesn't smoke, or try to get anyone to start smoking. It's obviously healthier to not drink or smoke. I'm just giving my view... 8)
