I'm a Washington resident, and to be truthful, I don't like the new law. While technically it's legal, the only authorized way to aquire weed is through a state-run store...which do not exist yet, and will not, for at least another year.
You are not allowed to grow your own, because the state wants you to pay taxes on it. Yeah, like I'm really thrilled with that...
The DUI provisions appear to be a wild-assed guess as to the amount of THC that causes enough intoxication to impair driving, and I still haven't found what studies they based these figures on.
The only part that makes me happy is that now the odor of weed is no longer probable cause for a search of you, your car, or your home.
Umm, yeah. I think I'll be staying under the radar, just as I have for the last 40 years or so.
