A drug is any substance that causes a change in an organism's physiology or psychology when consumed. Consumption of drugs can be via inhalation , injection , smoking , ingestion , absorption via a patch on the skin, suppository , or dissolution under the tongue. In pharmacology , a drug is a chemical substance, typically of known structure, which, when administered to a living organism, produces a biological effect.
Drug addiction, also called substance use disorder, is a disease that affects a person's brain and behavior and leads to an inability to control the use of a legal or illegal drug or medication. Substances such as alcohol, marijuana and nicotine also are considered drugs. When you're addicted, you may continue using the drug despite the harm it causes. Drug addiction can start with experimental use of a recreational drug in social situations, and, for some people, the drug use becomes more frequent. For others, particularly with opioids, drug addiction begins with exposure to prescribed medications, or receiving medications from a friend or relative who has been prescribed the medication. The risk of addiction and how fast you become addicted varies by drug.

Pharmacology, or the study of drugs and medications, is a complicated subject. One of the ways to make it easier to understand is to have a good knowledge of drug classification, or the system by which various drugs are grouped together. Drugs are categorized in a variety of different ways. In the pharmaceutical industry, drugs are grouped according to their chemical activity or conditions that they treat. There are many reasons to classify drugs, ranging from understanding the usefulness of particular types of drugs to formulating treatment plans based on chemically similar drugs. In the world of illicit and abused drug use, there are essentially 7 different types of drugs. Each has its own set of characteristics, effects, dangers, and side effects.

Drug and Alcohol Dependence is an international journal devoted to publishing original research, scholarly reviews, commentaries, and policy analyses in the area of drug , alcohol and tobacco use and dependence. Articles range from studies of the chemistry of substances of abuse , their actions at molecular Articles range from studies of the chemistry of substances of abuse , their actions at molecular and cellular sites, in vitro and in vivo investigations of their biochemical, pharmacological and behavioural actions, laboratory-based and clinical research in humans, substance abuse treatment and prevention research, and studies employing methods from epidemiology, sociology, and economics. The goal of the journal is to provide researchers, clinicians, and policy makers access to material from all perspectives in a single journal in a format that is understandable and which has received rigorous editorial review. The hope of its editors is to promote mutual understanding of the many facets of drug abuse to the benefit of all investigators involved in drug and alcohol research, and to facilitate the transfer of scientific findings to successful treatment and prevention practices. Drug and Alcohol Dependence is currently being distributed to all the members of the College on Problems of Drug Dependence CPDD , the oldest scientific organization in the United States concerned with research on problems of drug dependence.

MDMA—mild hallucinogenic effects; increased tactile sensitivity, empathic feelings; treatment to significantly reduce or stop their drug use and that the best outcomes also describes different types of science-based treatments and provides.
Depressant substances reduce arousal and stimulation. They do not necessarily make a person feel depressed. They affect the central nervous system, slowing down the messages between the brain and the body. They can affect concentration and coordination.
We live in a world where incredible drugs exist to treat many conditions that seemed untouchable in the past. In a report that looked at U. However, the impressive availability of medications also increases the possibility of drug interactions. This can cause the medication to be less or more potent than intended or result in unexpected side effects.
Research shows. You probably know that drugs affect feelings and moods, judgment, decision making, learning, and memory. Some of these effects occur when drugs are used at high doses or after prolonged use, and some may occur after just one use. But it is not only injection drug users who risk contracting or spreading infections. Mental Health Effects Drug abuse might affect an existing mental disorder or result in one.
Drugs can be classified into different categories based on their chemical ingredients and their effects on users. Here are the five main categories and some information about each:.
Drugs are chemical substances that can change how your body and mind work. They include prescription medicines, over-the-counter medicines , alcohol , tobacco , and illegal drugs. Drug use is dangerous. It can harm your brain and body, sometimes permanently. It can hurt the people around you, including friends, families, kids, and unborn babies.
Physicians have long recognized that different types of drugs affect people differently. Nonetheless, drugs may be categorized or classified according to certain shared symptomatologies or effects. The DRE categorization process is premised on these long-standing, medically accepted facts. DREs classify drugs in one of seven categories: central nervous system CNS depressants, CNS stimulants, hallucinogens, dissociative anesthetics, narcotic analgesics, inhalants, and cannabis. Drugs from each of these categories can affect a person's central nervous system and impair a person's normal faculties, including a person's ability to safely operate a motor vehicle. CNS depressants slow down the operations of the brain and the body.
Medications or pharmaceuticals are also drugs and are regulated differently dependent on their level of health risk. Short-term health harms. Short-term health harms are those that can occur as a result of an episode of use, or, in the case of medications, inappropriate use. These vary markedly depending on the drug being used type, amount etc and may be from the drug itself or from the manner in which the drug is taken. For information about the short-term health effects of a specific illicit drug, visit the page called Misused substances. A person is described as having taken an overdose if they suffer a medical emergency as a result of accidentally or intentionally using a larger amount of a drug than normal. This type of overdose can result from both taking too much of a prescribed drug or too much of an illicit drug or a combination of drugs.
