Can you gave me article on drug addiction
Answers
Alcohol: beer, wine, liquor
Caffeine: coffee, tea, kola nut
Cannabis: marijuana, hashish, hash oil
Hallucinogens: phencyclidine (PCP), d-lysergic acid diethylamide (LSD), psilocybin (magic mushrooms), peyote
Inhalants: inhaled spray paints, markers, glues
Opioids heroin, prescription pain-killers, methadone
Sedatives, hypnotics, or anxiolytics: barbiturates, benzodiazepines, antihistamines
Stimulants: cocaine, amphetamines, other stimulants
Tobacco: cigarettes, cigars, snuff, chewing tobacco, e-cigarettes
Other (or unknown)
These groupings aren’t perfectly distinct (many drugs fall into more than one category), but can be helpful in understanding how the characteristics of each drug make it more or less likely to be used in excess.
What makes a substance addictive?
The common characteristic of all addictive substances is that they activate the brain’s reward system, either directly or indirectly.
The primary role of the reward system is to encourage you to satisfy the needs important for survival (eating, drinking, having sex). Although the system itself is complex, it operates on a simple principle: if doing something feels good, you’re more likely to do it again. When your needs are met, a region in the midbrain called the ventral tegmental area (VTA) releases a little surge of the chemical dopamine, which makes you feel satisfaction and pleasure. The VTA sends dopamine to several areas of the brain, including:
Amygdala: sensing and expressing emotions
Nucleus accumbens: motor control
Hippocampus: memory formation
Prefrontal cortex: attention and planning behavior
These brain regions respond to the dopamine surge in ways that guide your memory, attention, and behavior toward repeating whatever triggered the pleasurable chemical release. The shape and function of your brain literally changes as a result of these reactions!^2

Always remember: Cells that fire together (in response to the presence of dopamine) wire together (strengthen their connections, so it's easier to fire together in the future).
Your reward system doesn’t respond only to your basic needs. As you grow and develop, it also begins to respond to the satisfaction of needs that are important for more abstract goals (like getting a good grade on a test). Any substance that (either directly or indirectly) increases the release of dopamine has the potential to hijack your reward system, making you very motivated to use the substance again. For some people, the motivation for substance use can begin to outweigh the drive to satisfy other needs (getting enough sleep, eating enough, saving money) leading to harmful effects. As a rule of thumb, the relative addictiveness of a drug is measured by the intensity of the effect it has on the release of dopamine.

Explanation:
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 medicine. Substances such as alcohol, marijuana and nicotine also are considered drugs.
Drug addiction weakens a person's immune system. It causes various mental and physical illnesses. The problems can be both short term and long term. The kind of drug a person consumes, how he consumes it, how much he consumes it and the period of time for which he takes it form the basis of different health problems.
An addiction is a very strong urge to do something that is hard to control or stop. If you use cigarettes, alcohol, or drugs like marijuana (weed), cocaine, and heroin, you could become addicted to them. They can really hurt you and could even kill you
