i'm thinking that 420 was speaking of Cannabis itself never killing anyone.

like any substance if you mix it with stupidity or bad choices you will have bad results.
who uses Cannabis?
smart people/stupid people
honest people/dishonest people
safe drivers/unsafe drivers
the list is as long as the list of how many different types of people there are.

no one should drive if they are impaired. there have been studies that showed people under the influence of Cannabis were actually safer drivers. they are somewhere in Cannabis facts i think. if i remember correctly there was a u.k. study and a canadian study. i'm not recommending anyone drive while/after using Cannabis, just sayin'.
