114) of respondents from states where MJ is legal stated they have not seen an increase in MVC since MJ was legalized. At the TX trauma center, only 4% of patients involved in a vehicular trauma tested positive for MJ, 21% of patients had the presence of ETOH, and 3% had both. For both MJ and also ETOH, the incidence remained the same each year. In CA, there was little yearly variation in the incidence of patients that tested positive for MJ (23%), ETOH (50%), and both (7%). In addition, the incidence of MJ was essentially unchanged after the decriminalization law was passed in 2010. Conclusion The prevalence of cannabis and alcohol varies among the states studied, TX and CA. The impact of decriminalization of marijuana did not seem to affect the incidence of drugged driving with marijuana in CA.
