Teens, Marijuana, and Driving: What You Need to Know in the South Bay and Southern California

As marijuana becomes more accessible across California, a growing concern for parents, educators, and community leaders in the South Bay—including areas like Torrance, Redondo Beach, Hermosa Beach, and Manhattan Beach—is the rise in teen driving under the influence of cannabis. While many teens may view marijuana as “safer” than alcohol, the reality is that driving high is both illegal and dangerous, with serious legal and life-altering consequences.

Is it Illegal for Teens to Drive Under the Influence of Marijuana?

Yes. In California, it is illegal for anyone—regardless of age—to drive under the influence of marijuana. For teens under 21, the law is even stricter. Under California’s zero-tolerance policy, it’s illegal for minors to drive with any detectable amount of THC (the psychoactive component of cannabis) in their system.

Why Is Driving High Dangerous?

While some teens believe marijuana doesn't impair them like alcohol does, research shows otherwise. THC affects:

Reaction time
Coordination
Attention span
Judgment

All of which are critical for safe driving. Even “a little high” can result in delayed decisions or misjudging distances—putting everyone on the road at risk.

Consequences of Driving Under the Influence (DUI)

For teens, a DUI conviction in Southern California can have lasting effects:

License suspension
Hefty fines and court fees
Mandatory drug education programs
Criminal record
Increased insurance rates
Limited college or job opportunities

In addition to legal consequences, getting into an accident while impaired could result in injury or death—and irreversible trauma for all involved.

The South Bay Perspective

In communities like Manhattan Beach, Hermosa Beach, and Torrance, law enforcement is placing increased focus on detecting marijuana-related DUIs, especially among young drivers. With the rise in dispensaries and cannabis-infused products, it’s more important than ever for teens and families to understand that just because it’s legal for adults doesn’t mean it’s safe—or legal—for everyone.
