I seriously doubt you've ever seen it in public here. I've lived here 42 years, and I have never seen marijuana in private, much less in public. It is still illegal to smoke in public even after this half-ass legalization attempt. In fact, this fake legalization effort has actually clarified the law on just how much more illegal it is now. The SPD will still ticket you. The ticket is only $27, but it certainly is illegal.
Born and raised in Seattle (45 years) and I can state for a fact that me & my friends have no problem smoking it outside, on the street. I pass by people almost every day on Capital Hill that are smoking since the decriminalization of it. Before that, I'd run into people smoking weed outside about once a week.
And I'm going to point out, if you've never seen anyone smoke marijuana in private, I'm not surprised you haven't seen anyone smoke it in public. You seem to have a very sheltered life, mainly if you lived in Seattle for 42 years and haven't seen any sight of the mighty marijuana. Shit, I grew up in this christian home, where we had to go to church and follow all those rules. I was a pretty naive kid and a bit sheltered, but I not only had seen marijuana by the time I was in 6th grade, I'd seen peeps smoke it and knew what it smelt like. Yes, in Seattle, the place you claim no one smokes.
We don't care if smoking outside is illegal. We didn't care that smoking weed was illegal a year ago when we smoked it, we didn't care 20 years ago when we were smoking it. It didn't stop us. So thinking that saying it's illegal and you'll get ticketed by the Seattle Pigs is really pointless. We don't give a fuck. Either take a hit off that joint, or pass it.
