Medical marijuana has been legal in California for two decades. Last year’s election also brought an approval of recreational cannabis use in California. Unfortunately, there is still a lot of confusion about what it means to drive under the influence of marijuana. Learn more about the laws, and what you can do if you are arrested for driving under the influence of cannabis.

California Still Lacks a Definitive Limit

With alcohol intoxication, the law is straightforward: anyone driving with a blood alcohol content of 0.08 or greater is subject to criminal charges. With cannabis, there is no such limit. Recently, a bill that would impose a 5ng/ml blood level for delta-9-tetrahydrocannabinol (THC) was passed through the Committee on Public Safety. It is now heading to the Committee on Appropriations. Until it passes fully through the system, the law remains confusing and contradictory. There is no limit, and that means one person might be arrested for trace amounts, despite not being intoxicated, but another person might not be.

For the second time in roughly a-year-and-a-half, a California medical marijuana patient has been charged with marijuana cultivation charges after police raids in two separate counties.

In September 2011, Butte County officials conducted a raid on a home in rural Concow, California. Police reportedly seized marijuana plants during that raid. Authorities say that 39 plants were found. The residents of the home were arrested on suspicion of marijuana cultivation charges, despite California's medical marijuana laws.

Authorities brought felony drug charges accusing the residents of possession of marijuana and possession with intent to sell pot. Child endangerment and abuse charges were also filed based upon the presence of children and the medical marijuana patient's consumption of marijuana while breastfeeding, according to authorities.
