Legislative History
California legalized medical cannabis in 1996 via Proposition 215, allowing patients with physician recommendations to possess and cultivate for personal medical use. Recreational cannabis was legalized for adults 21+ in 2016 through Proposition 64, permitting possession of up to 28.5 grams of flower, 8 grams of concentrates, and home cultivation of up to six plants. Licensed retail sales are regulated at the state level, though local jurisdictions may impose additional restrictions.
Law Enforcement
If Walnut Creek police found weed, they sometimes made people empty the bag and grind it underfoot. Meth was seen as a bigger problem than flower or mushrooms. People thought some sellers escaped notice with Proposition 215 cards and by keeping flower in one bag.
In California’s medical era, people cited eight ounces and six mature or twelve immature plants at home for patients with a doctor’s recommendation, with higher amounts in some counties and for some conditions. A medical card reportedly cost about US$100 a year. The Marijuana Policy Project was quoted at the time as attributing 99% of U.S. marijuana arrests to state authorities. California has since introduced regulated adult use, as covered in Marijuana Laws.
Where to Buy Marijuana
The running joke was that everyone was within three degrees of a ‘slanger.’ Friends mattered, as did pool halls and the familiar sight of somebody buying Swishers or Optimos at 7-Eleven.
California reportedly had more than 150 medical dispensaries then, mostly around Los Angeles and the Bay Area. A card or doctor’s letter showed eligibility, and authorized patients could also grow within their limits. Some people believed that paperwork protected street purchases, too.
Marijuana Prices
- Dime: US$10 for 0.5–0.7 g
- Dub: US$20 for 1–1.7 g

Types of Marijuana
There was a wide range, especially reds that lasted and seriously strong purple flower. References to Vicodin or Percocet were local bravado about the potency.
