I know that, but im not going to avoid somthing that I enjoy doing because theres a chance of addiction. I feel no desperate urge to smoke, I merely like doing it. I still cant see why its illegal, if it was a monitored substance, id be ok with that, at least there would be some control over it, the MAN could even subsidies it to undercut the dealers. But when I hear people going mad about how bad it is, without giving a reason just angers me, time to smoke..
One of the most common reasons people stop smoking weed altogether is paranoia/nasty mood swings.
I have 2 family members who gave it away because it was just screwing both their lives up. Excessive marijuana use has been documented in casenotes of many patients with schizophrenia.
The truth is that ciggerettes cause cancer, and alcohol can lead to domestic violence and road accidents. I wouldn't buy weed and smoke it, but I understand why people do, what they enjoy about it and how they justify it.
There is a theory that trying weed can lead to experimentation with other, harder drugs. I honestly don't know how much truth there is to that.
