A chronic disease characterized by uncontrolled drinking and preoccupation with alcohol.
Alcoholism is the inability to control drinking due to both a physical and emotional dependence on alcohol.
Symptoms include a strong need or urge to use alcohol. Those with alcohol use disorder may have problems controlling their drinking, continue to use alcohol even when it causes problems, or have withdrawal symptoms when they rapidly decrease or stop drinking. Treatment involves counseling, such as behavioral therapy, and medications that reduce the desire to drink. Some people need medical detoxification to stop drinking safely. Mutual support groups help people stop drinking, manage relapses and cope with necessary lifestyle changes.
Opioids are a class of drugs that derive from, or mimic, natural substances found in the opium poppy plant. Opioids work in the brain to produce a variety of effects, including pain relief. As a class of substances, they act on opioid receptors to produce morphine-like effects.
Physical and psychological reliance on opioids, a substance found in certain prescription pain medications and illegal drugs like heroin. Opioids are prescribed to treat pain. With prolonged use, pain-relieving effects may lessen and pain can become worse. In addition, the body can develop dependence. Opioid dependence causes withdrawal symptoms, which makes it difficult to stop taking them. Addiction occurs when dependence interferes with daily life. Taking more than the prescribed amount or using illegal opioids like heroin may result in death. Symptoms of addiction include uncontrollable cravings and inability to control opioid use even though it's having negative effects on personal relationships or finances. Treatment varies but may include discontinuing the drug. Medications such as methadone can help alleviate the symptoms of withdrawal and cravings. Pairing medication with inpatient or support programs generally has the most success.
Heroin, also known as diacetylmorphine and diamorphine among other names, is a morphinan opioid substance synthesized from the dried latex of the Papaver somniferum plant; it is mainly used as a recreational drug for its euphoric effects. Medical-grade diamorphine is used as a pure hydrochloride salt.
Fentanyl, is a powerful synthetic opioid that is similar to morphine but is 50 to 100 times more potent. Like heroin, morphine, and other opioid drugs, fentanyl works by binding to the body's opioid receptors, which are found in areas of the brain that control pain and emotions.8 After taking opioids many times, the brain adapts to the drug, diminishing its sensitivity, making it hard to feel pleasure from anything besides the drug. When people become addicted, drug seeking and drug use take over their lives.

Cannabis, also known as marijuana or weed among other names, is a psychoactive drug from the cannabis plant. Native to Central or South Asia, the cannabis plant has been used as a drug for both recreational and entheogenic purposes and in various traditional medicines for centuries.
The definition of marijuana (Cannabis) dependence (addiction) contains three critical elements. These are (a) preoccupation with the acquisition of marijuana, (b) compulsive use of marijuana, (c) relapse to or recurrent use of the marijuana. The manifestations of abnormal marijuana use may assume many forms. Medical, psychiatric, neurological, traumatic, and sociological sequelae occur commonly in acute and chronic marijuana use.
Methamphetamine was developed early in the 20th century from its parent drug, amphetamine, and was used originally in nasal decongestants and bronchial inhalers. Like amphetamine methamphetamine causes increased activity and talkativeness, decreased appetite, and a pleasurable sense of well-being or euphoria. However, methamphetamine differs from amphetamine in that, at comparable doses, much greater amounts of the drug get into the brain, making it a more potent stimulant. It also has longer-lasting and more harmful effects on the central nervous system. These characteristics make it a drug with high potential for widespread misuse.
Methamphetamine has been classified by the U.S. Drug Enforcement Administration as a Schedule II stimulant, which makes it legally available only through a nonrefillable prescription. Medically it may be indicated for the treatment of attention deficit hyperactivity disorder (ADHD) and as a short-term component of weight-loss treatments, but these uses are limited and it is rarely prescribed; also, the prescribed doses are far lower than those typically misused.
Benzodiazepines are depressants that produce sedation and hypnosis, relieve anxiety and muscle spasms, and reduce seizures. The most common benzodiazepines are the prescription drugs Valium®, Xanax®, Halcion®, Ativan®, and Klonopin®.
Benzodiazepines can lead to both physical and psychological dependence. If you become dependent on the drugs, you can have withdrawal symptoms and even seizures when you suddenly stop taking them. Only a very small percentage of people who take normal doses for short periods will become dependent on benzodiazepines. It can be hard to tell the difference between withdrawal symptoms and anxiety. Withdrawal symptoms usually show up anywhere from 3-4 days to 2 weeks after you last use the drug. But they can appear earlier with shorter-acting types of benzodiazepines.
