Subject: Health Check: what makes it so hard to quit drugs?
The brain becomes primed to repeat drug taking over and over without actually thinking about it. When the dopamine system is damaged in that part of the brain, it makes it much harder to think through consequences and make considered decisions, so drug use becomes more automated. The wiring of the dopamine reward system makes it compelling to use drugs, and the damage to the system makes self-regulation more difficult. The brain and body adapt over time to taking drugs and react when the alcohol or other drugs leave the system.
- Alcohol and other drugs eventually make their way into the brain via the bloodstream and Once there, they affect how messages are sent through the brain.
- Every drug affects different neurotransmitter pathways in different ways. Some affect more than one neurotransmitter.
- When large amounts of dopamine are released, the brain has trouble keeping up production and can temporarily run out of dopamine.
"Every drug affects different neurotransmitter pathways in different ways. Some affect more than one neurotransmitter. But most drugs impact the dopamine system in some way."
