3. Rapid Eye Movement
One sign of anti-anxiety drug abuse is involuntary rapid eye movement. You may notice people who are taking Xanax at a party having eyes that are constantly moving around. It is almost like their eyes are vibrating in their heads. The best way to see this is to have the person look to the left or to the right. We’ve all seen police officers ask suspected drunk drivers to follow their fingers back and forth. They aren’t testing to see if the driver can focus on their fingers. They are actually testing for rapid eye movement.
