Signs of Drug Abuse

Even when drug abuse is suspected, it is often very difficult to identify which drugs are being used, which can only be really determined through professional drug testing.

However, the Substance Abuse and Mental Health Services Administration (SAMHSA) has published information on the signs of drug abuse that might be useful where drug tests are not available:

  • Narcotics: Lethargy, drowsiness, euphoria, nausea, constipation, constricted pupils, slowed breathing
  • Hallucinogens: Trance-like state, excitation, euphoria, increased pulse rate, insomnia, hallucinations
  • Alcohol: Slurred speech, impaired judgment and motor skills, incoordination, confusion, tremors, drowsiness, agitation, nausea and vomiting, respiratory ailments, depression
  • Depressants: Drowsiness, confusion, incoordination, tremors, slurred speech, depressed pulse rate, shallow respiration, dilated pupils
  • Cocaine/Crack Cocaine: Excitability, euphoria, talkativeness, anxiety, increased pulse rate, dilated pupils, paranoia, agitation, hallucinations
  • Inhalants: Slurred speech, incoordination, nausea, vomiting, slowed breathing
  • Marijuana: Mood swings, euphoria, slow thinking and reflexes, dilated pupils, increased appetite, dryness of mouth, increased pulse rate, delusions, hallucinations
  • Stimulants: excitability, tremors, insomnia, sweating, dry mouth and lips, bad breath, dilated pupils, weight loss, paranoia, hallucinations
  • Tobacco: Smelly hair, clothes, and breath; yellowing of teeth; coughs; increased asthma attacks; shortness of breath and poorer athletic performance. After only a few weeks, users of spit tobacco can develop cracked lips, white spots, sores, and bleeding in the mouth
