I think pot is most likely a no brainer (<-pun?). My only concern are DUIs going up.
Marijuana involved in 12 percent of Colorado State Patrol DUI cases
1 in 8 of all DUI citations involved pot, that's not insignificant but at the same time does that equate to the same number of accidents or if you can really compare alcohol and pot impairment and also, how many people were cited for marijuana DUI cases before it was legal, maybe no difference at all though I suppose the crime was more serious.
Some people drive to secluded areas to smoke because the smell is a giveaway if they do it at home, especially in an apartment, which would result in cops being called. So....they have to drive. Still wrong to drive impaired....yes...but which is the lesser evil??
Legalize it and let people sit at home and smoke it.
Read some of Eddie Bravos stuff I recommended to OldSchool.
He nails it. He blasts people who drive high. He says weed makes you more of whatever you already are. If you're a dumbass it makes you more of a dumbass so he says dumbasses shouldn't smoke (just like booze). But nice people get nicer. And in reality...most people are nice.
