Driving Under the Influence of Hallucinogens

Hallucinogenic drugs are one of seven categories of drugs that Drug Recognition Experts look for in a driving under the influence evaluation.

This article discusses the effects and signs of hallucinogenic drug use.

The hallucinogenic drugs include LSD, Mushrooms, Peyote, and Mescaline.

Drug Recognition Experts are officers trained to determine if a driver is impaired by drugs. The Drug Recognition Expert (DRE) looks for signs of drug use and impairment and then makes a guess about which type of drug a person may have used.

The DREs have divided commonly used drugs into seven categories, one of which is hallucinogenic drugs. Each category of drugs produces different side effects and signs of use. The DRE will ask a driver to perform a series of tests, and then performs an evaluation of the driver.

The results of the test are used by the DRE to guess which type of drug a driver used (if they don’t already know from admissions or a search).
