A UC Berkeley Cannabis Research Center study finds large, licensed farms on California's central coast are helping push out illegal growers more effectively than crackdowns and bans. Many of these farms are venture-capital financed and vertically integrated.

  • Operators: Licensing costs $50,000 to over $100,000 and can take one to two years, with infrastructure standards like engineered roads and compliant irrigation. Small operators face heavy barriers, while large players stack multiple smaller licenses.
  • Investors: Venture-backed, vertically integrated farms controlling farming, distribution and retail are gaining ground in California. Licensing costs and infrastructure requirements favor well-capitalized operators, and a loophole lets large players stack licenses.
  • Do now: Audit your licensing timeline and budget against the $50,000 to $100,000-plus range and the infrastructure standards, including roads, irrigation and water storage, before committing capital to a California site.

Regulated cannabis farms are the best defense against illegal growers than government crackdowns and bans. That’s according to a new study from UC Berkeley Cannabis Research Center.

The researchers looked at a surge in large, licensed cannabis farms along California’s central coast, which are often financed by venture capital and utilize vertical integration by controlling farming, distribution, and retail.

Researcher Christopher Dillis, who is involved with the study, said licensing can cost cannabis growers between $50,000 up to over $100,000, as it encompasses extensive permits and regulations, reported The Daily Californian. Moreover, the process can take up to 1–2 years due to sluggish state bureaucracy.

In order to be licensed, a cannabis farm has to meet infrastructure standards such as engineered roads, compliant irrigation systems, and proper water storage. For farms that have been operating in the space without a license, it’s hard to meet these requirements, as they are often located in remote areas that are difficult and expensive to modernize to current code standards.

Penalties for illegal cultivation are another deal-breaker as they are severe, reaching up to $30,000 per day in Los Angeles County, for example. That said, licensed farms reportedly provide “anonymous tips” to authorities about nearby unlicensed growers, Dillis said.

Even though the Golden State initially “favored” small businesses in terms of license issuance, some farmers utilized a loophole in the law that allowed large operators to “stack” multiple smaller licenses.
