Yes, weed is legal in California for both medical and recreational use. Proposition 64, also known as the Adult Use of Marijuana Act, was passed in November 2016, legalizing the recreational use of marijuana for adults 21 and older. The sale and cultivation of marijuana for recreational purposes are also permitted, with regulations in place for licensing and taxation. Additionally, California was the first state to legalize medical marijuana with the passage of Proposition 215 in 1996, allowing patients with qualifying medical conditions to access and use marijuana for treatment.
It's important to note that there are still regulations and restrictions in place regarding where marijuana can be consumed, how much can be possessed, and where it can be purchased. Local municipalities in California can also enact their own regulations on the sale and cultivation of marijuana, so it’s important to familiarize yourself with the specific rules in your area.
