More Information About California Drug Laws

The state of California presently has a medical marijuana law, but the California Supreme Court has held that a company may decline to hire a candidate who tests positive for marijuana, even if the drug is lawfully prescribed for a disability. Any employer who is not employing someone, or dismissing someone for use of medical marijuana, needs a widespread drug free workplace policy in place.

Additionally, it is not simple or acceptable to drive while under the influence. In a quote from a California Highway Patrol officer to Capital Public Radio, it was stated that regarding Marijuana, "It has to be sealed in a container. The seal cannot be broken. And if it is in an open container, it would have to be locked away in a place like the trunk."

Companies in California can require employees to succumb to sensible suspicion testing, given specifying that the suspicion is based on real evidence. Supervisors should take training in identifying signs and indications that would lead to a rational suspicion drug test.

Random Drug Testing

Random drug and alcohol testing in California should be reduced to safety-sensitive positions. Courts have supported random drug testing for safety-sensitive positions, but not for non-safety sensitive positions. Of course, random drug and alcohol testing are mandatory for companies regulated by the Department of Transportation (DOT) or transportation companies regulated by the Public Utilities Commission (PUC).

Pre-Employment Drug Screening

For Pre-Employment drug screening in California, it is important to make the job offer and then run the drug test, so that the results will be acknowledged before the employee is essentially starting work or going on the payroll. This is always imperative because you do not want to put someone to work and then have to dismiss them a few days later if you obtain positive results.

Companies that have contracts or grants from the State of California are required to uphold a drug-free workplace program. This is mandatory by California's Drug-Free Workplace Act of 1990.
