Ok so it makes your reaction slower and more "careful", what happens when I small kid runs out in the middle of the road and as your reaction time is slower you dont hit the brake fast enough and you slam into this child. Does that make you more careful?
Fair enough most people do it at home or with mates but surely there is something wrong if you need a drug to make you interessting. Do you need to be taking drugs to watch TV or to make your friends like you? I find that very sad. The problem with weed is that soon enough the buzz from that isnt enough so people go onto class A. A friend of a friend did this and went on to herion and she died. It just doesnt seem worth it to me.
Also paranoia is not a good thing it can make you act out. (I know loads of stoners) They all went on a camping trip and got stoned but thought some was outside watching them, so the idiots went out and started hitting what they thought was someone. Turned out to be a light but still it couldve been someone.
