After alcohol, marijuana is the drug most commonly linked to impaired driving. It can slow your reaction time and ability to make decisions. The risk of impaired driving associated with marijuana in combination with alcohol appears to be greater than that for either by itself.


Is there a legal limit for Marijuana?

Laws vary from state to state, but in California, it is unlawful to drive while under the influence of marijuana by Vehicle Code 23152. "Under the influence" is not specifically defined in the statute, which means that there is no "safe" amount you can smoke and drive. If you are planning on driving, the safest route is not to smoke at all.


What are the penalties for driving under the influence of marijuana?

As with other forms of DUI, the penalties for VC 23152(e) DUI of marijuana in California increase with each conviction for any form of DUI--including DUI of alcohol and DUI of drugs--within a 10-year period.
