Marijuana DUI Attorney

Currently it is legal in California to smoke marijuana recreationally as long as you are over 21.  However, it remains illegal to drive if you are under the influence of marijuana or any other drug.  What does it mean to be under the influence?  California defines “under the influence“ as being so impaired by the drug as to no longer being able to drive a motor vehicle with the caution characteristic of a sober person.  Simply having THC or cannabinoids in your blood is not enough, you must have so much that it no longer allows you to drive safely.


Matthew is skilled in discrediting police conclusions about levels of impairment from drugs.  For example. many officers will rely on certain eye conditions to opine a person is under the influence of drugs, however most cops are inadequately trained to properly perform eye tests and Matt can often show this during his cross examinatio.
