SAN DIEGO (CBS 8) - More drivers in California get behind the wheel under the influence of drugs, compared to those who drive drunk, according to a new statewide survey.
State officials are warning against "high driving" after the survey found that one of every seven drivers on the road on weekend nights are under the influence of drugs. That's nearly twice the number of drivers with alcohol in their system.
The survey was conducted by the California Office of Traffic Safety.
Researchers found that 14% of drivers tested positive for driving while under the influence of drugs, both illegal and prescription. Among those drivers, about half were under the influence of marijuana and about 5% were under the influence of prescription drugs.
Slightly more than seven percent of drivers in the survey tested positive for driving with alcohol in their system.
The survey results were taken from more than 1,300 drivers who agreed to provide breath or saliva samples at law enforcement checkpoints set up in nine California cities between 10 p.m. and 3 a.m. on Friday and Saturday nights.
