Substance Use Disorders

Alcoholism is defined as a chronic disease characterized by compulsive use of alcohol, resulting in significant impairment of social, occupational, or other important aspects of functioning. There are several types of alcoholism, including acute intoxication, withdrawal, and physical dependence. Acute intoxication occurs when someone consumes alcohol excessively and experiences symptoms of intoxication (e.g., feeling drunk). Withdrawal refers to the physiological effects of stopping drinking. Physical dependence is a condition where repeated exposure to alcohol causes tolerance to its effects and results in withdrawal if alcohol consumption stops.

Substance Abuse

Substance abuse is any type of drug or substance use disorder. A substance use disorder is a pattern of behavior that begins with the recreational use of drugs or alcohol and progresses to compulsive use, continued use despite harm, and loss of control over use. People who have a substance use disorder may experience problems at work, school, home, or with their relationships.

Drug Addiction

Drug addiction is a chronic relapsing brain disease that develops after prolonged use of a psychoactive substance. Drugs affect the body’s reward system, causing changes in how people think, feel, and behave. These changes lead to cravings and a strong desire to take the drug again. Over time, these behaviors become automatic and cause serious problems in a person’s life.

Cocaine Addiction

Cocaine is a white crystalline alkaloid derived from coca leaves. It is a central nervous system stimulant that affects both the central nervous system and the cardiovascular system. Cocaine is often used recreationally and is associated with euphoria, increased alertness, decreased appetite, insomnia, and anxiety.

Heroin Addiction

Heroin is a highly addictive opioid analgesic drug that is derived from morphine. Heroin is a powerful narcotic painkiller that is commonly injected intravenously. It produces feelings of euphoria, relaxation, and calmness. Heroin is often abused due to its high potential for addiction.

Marijuana Addiction

Marijuana is a flowering herbaceous perennial plant belonging to the Cannabaceae family. Its genus name comes from the Latin word marijuana, meaning “grass”. Cannabis sativa L. is the scientific name for marijuana. It contains many cannabinoids, including delta-9 tetrahydrocannabinol (THC), cannabidiol (CBD), cannabinol (CBN), cannabichromene (CBC), and tetrahydrocannabivarin (THCV). THC is the primary active ingredient responsible for producing the psychotropic effects of cannabis.

Methamphetamine Addiction

Methamphetamine is a colorless, odorless, bitter crystalline solid. It is a potent central nervous system stimulant and sympathomimetic amine. Methamphetamine is chemically similar to amphetamine and is classified as a Schedule II controlled substance under the Controlled Substances Act.
