California became a center for weed long ago, as early as the beginning of the 1900s.
In the 1950s-1970s, the beatnik and hippie movements and the related counter-cultural art and activism popularized weed consumption for mainstream America.
By the early 1970s, California already held a prominent place in the world of cannabis cultivation and consumption.
Weed has been grown on family farms in the Northern California counties for several generations.
The three most abundant cannabis counties in Northern California are collectively known as the Emerald Triangle.
Weed has also been grown all throughout central and southern California for the same period of time.
As the U.S. government cracked down on and criminalized weed, the traffic in weed coming from Mexico increased.
As a result of heavy criminalization and the introduction of the War on Drugs, Californians were put in competition with organized gangs and cartels that came from central and South America as well as from Asia.
In the 1980s and 1990s, police heavily monitored and aggressively arrested people in urban communities, usually Black and Latino communities in poorer parts of town. As a result, growing outdoors was too dangerous, and new technologies in indoor farming were coming online. Urban cultivators found that they could grow amazing weed in the highly controlled environment of indoor grows.
Today, weed is grown either indoor or outdoor, with each having its pluses and minuses.
By 2022, California was the largest market in the world for both the production and consumption of weed.
The largest market for weed inside of California is L.A. county by far.
One of the most significant locations for weed culture and cultivation in California is the Bay Area, including Oakland. The best most exotic, most flavorful weed is said to come from the Bay Area, in part due to its location in relation to the Emerald Triangle.
