I also think that people who smoke will not know the difference in other people who smoke.
I am not saying people that smokers are retards. I am saying that it does effect your short term and long-term memory. That laid back attitude your talking about is called laziness. It is a result of long-term memory loss. But hey, I am no scientist or anything. I just know what I see. Maybe all the potheads I know are an exception.
