sure they are not.....they may not abuse it but everyone that i mentioned smoked it either back when, or still occasionally .......one guy Crick used to do acid on top of the weed....your problem Weasel is you refuse to accept anything that may not be a negative about pot.....but dont worry your ignorance is not confined to you alone....
I'm not worried and I wasn't born yesterday. However, yesterday's weed isn't today's weed and that something seldom brought up. Pot is definitely more along the lines of what a drug is than alcohol. Many or most adults drink to some degree and it doesn't alter their lifestyle. Pot use does somehow.
I remember a Joe Square kind of guy in the military that started smoking weed. The next thing we knew his car was painted every florescent color available, through lace doilies and was a changed man. How many beer drinkers do you know of that change like that. And it wasn't even good weed by today's standards.
