This argument will never end well, a lot of MJ smokers are in denial.
Marijuana smoke contains carbon monoxide
Marijuana smoke contains tar
Marijuana adversely effects your mind
Those are FACTS. Go look inside your bowl and see all the shit in there. Go talk to someone who has been smoking weed moderately for 20 years. Listen to how they talk, look at how they conduct themselves, look at their lifestyle.
Oh well....
