Addiction Treatment Interventions
When you use drugs for a long period, it might create alterations in other brain chemical processes and circuits as well. They have the potential to impair your judgement, ability to make decisions, memory, and ability to learn. These brain alterations, when combined, can make it difficult for you to resist the temptation to seek out and use drugs in ways that are beyond your control.
Most drugs cause the brain to "reward-circuit" which floods it with dopamine and makes one feel good. People are more likely to choose things that are good for their health, such as eating healthy and spending time with loved ones. The reward circuit causes people to keep doing the things they enjoy but are bad for them. This in turn leads people to take part again.
