Methods for quick qualitative and quantitative evaluation of drug intake are needed, especially during emergency situations such as drug overdose and alcohol intoxication. The electronystagmograph was used in an attempt to develop a non-invasive method for identification of drug intake, and to study the effects of alcohol and other drugs on the vestibular system. Results of the study reveal that alcohol, diazepam, opiates, barbiturates, cocaine, marijuana, and hallucinogenic drugs produce a characteristic printout pattern which can be evaluated qualitatively. This method is a practical, non-invasive, objective procedure that provides rapid assessment of quality of drug intake. Its potential uses are extensive, including such possibilities as evaluation of drug intake in emergency drug overdose situations, monitoring anesthesia during surgery, evaluating drug intake in women about to deliver, (as well as the effects on the newborn), and determining whether or not persons who are being tested on a polygraph are under the influence of drugs.
