Q: How will law enforcement (in a legal weed world) conduct sobriety tests on drivers? (Joseph B.)
Great question, Joseph. This is one of the major issues that's kept some legislators from backing legal weed.
The short answer is: There is no sobriety test — at least not the kind of test you're probably thinking of, like an alcohol breath test.
When police suspect a driver is driving under the influence of drugs, such as marijuana, they call in a drug recognition expert to perform a series of tests (usually involving the eyes) to determine whether the driver is intoxicated. A drug recognition expert, or DRE, is a police officer who's been specifically trained to spot drugged driving.
If New Jersey legalizes weed, you can expect the number of DRE officers to increase.
