Drug Abuse

Use and abuse of drugs or medicines may lead to addiction or dependence. You may hear drug abuse or addiction called substance use disorder. Examples of illegal drugs include amphetamines (also known as speed or crank), methamphetamines (meth), cocaine, heroin, bath salts, and hallucinogens (such as MDMA, ecstasy, PCP, mescaline, and LSD).

Xylazine is a sedative and pain reliever approved only for animals. It's not approved or safe for people. It's known by the street name tranq. Xylazine has been found in street drugs, especially heroin and fentanyl. It has been linked to overdoses and death. Severe side effects from xylazine include slow heart beat and breathing, low blood pressure, skin sores, and coma.

In some states, marijuana is an illegal drug. Medicines include prescription medicines, sedatives, and sleeping pills.

Social and personal problems

Once addiction or dependence happens, you are at greater risk for social and personal problems, including:

  • Craving for the drug and not being able to stop using even though you think you want to stop (psychological addiction).

  • Drug withdrawal symptoms if you stop taking the drug (physical dependence).

  • Loss of friends and family.

  • School or work problems.

  • Arrest, conviction, and jail sentence for possession of an illegal substance or for driving under the influence.

Health problems

Drug use and abuse also increase your risk of serious health problems, including:

  • Stroke, heart attack, heart failure, and kidney failure.

  • Accidental injuries to yourself or others while you are under the influence of a drug (in a car or at home).

  • HIV infection. This is a much greater risk if you use IV drugs.

  • Skin infections.

  • Sexually transmitted infections (STIs), such as herpes, chlamydia, and gonorrhea.

  • Severe and fatal infection of the heart valves if you use IV drugs.

  • Hepatitis B or C.

  • Dementia, mood disorders, persistent hallucinations (particularly with hallucinogens).

  • Dental problems from methamphetamine abuse.

  • Death from overdose.
