CO and WA Legalize Recreational Marijuana

I'm all for legalisation, and I think it'd be smart to legalise it. However, I'm not going to lie to myself and say people should drive while high. It's completely retarded and as much as I hate to pull the science card on these forums it's completely anecdotal to say that it won't have issues. Just because your friends seem to be decent drivers while under the influence of marijuana doesn't mean most Americans will be as good. Most Americans are idiots while driving anyway and car accidents are very high with drunk driving and other statistics. Why would you want to risk it and cause a possible increase of accidents while driving? It's silly.
