Symptoms of addiction to drugs or other substances may be subtle or overt:
- You’ve built up a drug tolerance. You need to use more of the drug to experience the same effects you used to attain with smaller amounts.
- You take drugs to avoid or relieve withdrawal symptoms. If you go too long without drugs, you experience symptoms such as nausea, restlessness, insomnia, depression, sweating, shaking, and anxiety.
- You’ve lost control over your drug use. You often do drugs or use more than you planned, even though you told yourself you wouldn’t. You may want to stop using, but you feel powerless.
- Your life revolves around drug use. You spend a lot of time using and thinking about drugs, figuring out how to get them, and recovering from the drug’s effects.
- You’ve abandoned activities you used to enjoy, such as hobbies, sports, and socializing, because of your drug use.
- You continue to use drugs, despite knowing it’s hurting you. It’s causing major problems in your life—blackouts, infections, mood swings, depression, paranoia—but you use anyway.
