Well, the dope is sure around. Apparently quite a bit of it, but it runs in certain circles mostly so only those exposed to it really know the depth of it. Benzos are just about everywhere, lol so IDK about that.
Obviously, weed is HUGE here. Some of the best growers in the world live in Washington too, people that have been doing it for decades.
Meth is a big problem too, I know 15 year olds who LOVE it.... plenty of it to go around, too.
The rave scene is pretty damn huge here, but a lot of the pills are SHIT. Some good crystal around if you can find it, but you need a testing kit.
Shrooms are more abundant here than just about anywhere else in the world, growing naturally fucking everywhere... so there's a ton of that too.
Acid is around, but hard to find. Some AMAZING liquid turns up every once in awhile though, but it's a small trickle, not a flood.
Oh, coke is pretty damn popular too.... but absolutely HORRIBLE quality.
Not many RCs, people mostly stick to what they know. All the classics are around though, and their impact is certainly visible.
