Answer:
Factors such as peer pressure, physical abuse, early exposure to drugs, stress, and parental guidance can greatly affect a person's likelihood of drug use and addiction.
Why does a person become an addict:
~When people begin using drugs, the way the brain functions begins to change. Drugs have an effect on the way the brain communicates, and they can affect the way nerve cells send, receive, and interpret information. There are two ways this disruption of the brain can happen:
○by imitating the brain’s natural chemical messengers
and...
○by overstimulating the “reward circuit” of the brain.“Tricking” your brain
by overstimulating the “reward circuit” of the brain.“Tricking” your brainThe brain’s response is different depending on the type of drug being used. For example, some drugs have a similar makeup as the neurotransmitters in the brain. Neurotransmitters are chemicals in the brain that allow the body to communicate. When drugs such as marijuana are introduced into the brain, their similarities in makeup can trick the brain and result in abnormal messages being sent. However, when other drugs, such as cocaine or meth, are introduced into the body, the nerves in the brain can overreact and release larger than normal amounts of neurotransmitters. These types of drugs can also interfere with the way the brain typically recycles chemicals, resulting in an overload of dopamine, which is responsible for emotions, movements, and pleasure/pain. Because dopamine produces a high, this is generally an enjoyable feeling. The body starts to associate this feeling with drugs, which in result means a person continues to use to reach that same high. As the body does with many substances, it eventually begins to adjust to the effects of the drug, until a higher dose of the drug is necessary in order to reach the same high as before. This is why a drug addict’s use likely escalates over time – because the body is becoming used to the substance and more is required to evoke the same high. This begins a vicious cycle because the addict will continue to use and continue to up the amount of drugs being used as their tolerance builds. In short, the brain can’t tell the difference between where pleasure is coming from and reacts the same way (by releasing dopamine) whether it be because of a drug, a monetary reward, a sexual encounter, exercising or eating something that tastes good.
