San Fernando Valley, CA (aka "The Valley"), which is a suburb of Los Angeles
Weed. We are known as San Fernamsterdam due to the huge number of cannabis dispensaries around. People drive from Los Angeles, Malibu, Santa Clarita, Simi Valley, West LA/Santa Monica, and San Gabriel Valley, even San Bernardino, just to come to the dispensaries here, even though most of those places have dispensaries of their own. They say the Valley has the best weed in the world, and I agree. Weed and weed smokers here are so common that there are more people smoking than drinking at kickbacks. It's considered "weird" if you don't smoke but do other drugs. The good think about the availability of really good weed is keeping kids away from dope/meth.
To be honest, you can find any drug here, for cheap. My circle of friends happens to have no tweakers/junkies, so I thought only weed/MDMA/LSD/shrooms were common, but when I spent 2 nights in jail for a felony charge until I posted bail, they were all drug addicts/ex-addicts/wife beaters, which was a relief because I was expecting rapists and killers, maybe I got lucky with the timing. I never knew about dope sickness until last year lol. I was like "fuck I hope this guy doesn't get me sick, that's the worst flu I've seen." He was coming off a $150-200+ daily black tar IV habit. Most of the people there had kicked IV heroin, messed with coke, and most of them still do meth, despite now "being clean." I met this 50 year old burnout that was picked up for coke, he had been doing coke/crack since he was 18. Fuckkkkk he was burned out, looked like he was 65-70, turned me away from ever trying stimulants.
The coolest guy there was my age, blonde kid with an British accent, 20, and was there for heroin poss. He had stayed clean for 3 weeks, had a bad day so he bought some dope and a rig, and proceeded to nod out and pass out in his car parked by a rec. park, needle in arm. First, people thought he was dead, so ambulance was called, then they saw the needle and called the cops. He didn't know how/why his jeans were replaced with jail pants, someone said it might have had blood on it, from the needle? Anyways, if you're out there, I hope you're still clean, dude. He was thinking about going on subs before his relapse.
