Polysubstance Abuse


Polysubstance abuse

is the abuse of 2 or more drugs that cause impairment or distress. Substances include alcohol, nicotine, marijuana, cocaine, heroin, methamphetamine, hallucinogens such as mushrooms, or inhalants such as paint thinner. Prescribed medicines, such as opioids for pain or benzodiazepines for anxiety, are also commonly abused.

Call your local emergency number (911 in the US) if:

  • You feel you might harm yourself or others.

Seek care immediately if:

  • You have a seizure.
  • You have chest pain and your heart is beating faster than usual.
  • You have new shortness of breath.
  • You are dizzy and lightheaded.

Call your doctor or therapist if:

  • You are using drugs and think you are pregnant.
  • You have withdrawal symptoms and want to start using drugs again.
  • You have questions or concerns about your condition or care.


  • Withdrawal medicines may be given according to the types of drugs you are abusing. Withdrawal from drugs can cause serious, life-threatening side effects. Certain medicines can help decrease your withdrawal symptoms and your desire for the drug. Ask for more information about the withdrawal medicines you may need.
  • Mood stabilizers may be given to help prevent or treat depression or anxiety caused by drug abuse and withdrawal.
  • Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell him or her if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.

Therapy and support

to help you stop using drugs:

  • Cognitive and behavioral therapy helps you change your thinking and behavior. It can help you develop plans to avoid the situations that make you want to use drugs. It also helps you cope with the feelings of wanting to use drugs. You may have individual or group therapy.
  • Contingency management helps you set drug-free goals with a therapist. You will decide ways to celebrate your success when you reach a goal.
  • Family therapy and support groups allow you and your family members to talk to and be encouraged by other people affected by drug abuse. You and your family members may attend together or separately. Ask your healthcare provider for information about programs in your area.

How polysubstance abuse affects unborn or newborn babies:

  • If you are pregnant or get pregnant while using drugs, you may have a miscarriage or give birth early. Your baby may be born addicted to the drugs.
  • Do not breastfeed your baby if you use drugs. Drugs pass from your bloodstream into your breast milk and affect your baby's health. Talk with your healthcare provider if you are using drugs and breastfeeding.

Follow up with your doctor or therapist as directed:

You may be referred to a specialist to treat health conditions caused by your drug use. This includes mental health, heart, or lung specialists. Write down your questions so you remember to ask them during your visits.
