Drug abuse and the rapid eye test.
Drug effects contribute to impaired eye movements and visual information processing. Only a small percentage of clinical conditions can cause a positive rapid eye test, therefore, drug use must be suspected and should be confirmed by body fluid analysis. A drug may not reach the urine for one to two hours, while eye signs occur within fifteen minutes after sniffing, inhaling, or injecting the drug. The rapid eye test is inexpensive, nonintrusive, and detects the actual influence of the drug on the body.
