Now a days, my brother is behaving abnormally, not at all showing interest in any activity. I suspect that he is taking drugs. To confirm this, first I want to know about physical symptoms of drug abuse. So, I searched information regarding symptoms in the net and would like to share them with you. A person who is addicted to drug suffers from unexpected weight loss or gain and change in eating habits like increase in appetite or loss of appetite. There will be poor physical coordination and walks slowly. They cannot sleep properly and wake up at unusual times. Their eyes will be red and watery, and pupil of eye may become larger or smaller than usual.
The intake of drug substance can be smelled on breath, body, or clothes. They have swollen face, cold, sweaty palms and shaking hands. They have irregular heartbeat and shakes of hands, feet or head can be observed. They always suffer from running nose and aggravating cough. They may be extremely hyperactive and talk excessively. They have needle marks on lower arm, leg, or bottom of feet. If these symptoms are observed then we can suspect that a person is taking drug.
