How do drugs affect the brain? - Sara Garofalo
TED-Ed・2 minutes read
Drugs alter brain cell communication through different administration methods, affecting behaviors, emotions, and cognition by manipulating neurotransmitters. Illegal substances like crystal meth and cocaine can have potent effects on the brain, impacting reward perception and mood regulation, leading to strict regulations due to their ability to permanently alter brain chemistry.
Insights
- Drugs impact the body by altering communication between brain cells, with different methods of administration affecting how quickly they affect the brain.
- Illegal drugs such as crystal meth, cocaine, and hallucinogens can significantly impact neurotransmitters like dopamine and serotonin, influencing reward perception, energy levels, and mood regulation, leading to strict regulations due to their potential to permanently alter brain chemistry with repeated use.

Recent questions
How do drugs affect the body?
Drugs impact the body by altering communication between brain cells, with various methods of administration affecting the speed at which they reach the brain. Orally taken drugs are the slowest, while inhaling or injecting drugs intravenously allows for faster absorption into the bloodstream. Once in the brain, drugs manipulate neurotransmitters to either inhibit or excite neurons, affecting behaviors, emotions, and cognition.
What neurotransmitters do drugs manipulate?
Drugs manipulate neurotransmitters like dopamine and serotonin in the brain. Different drugs like antidepressants, painkillers, and tranquilizers target specific neurotransmitters to alter brain function and perception. Illegal drugs such as crystal meth, cocaine, and hallucinogens have potent effects on the brain by impacting reward perception, energy levels, and mood regulation through manipulation of neurotransmitters.
Why are illegal drugs regulated?
Illegal drugs like crystal meth, cocaine, and hallucinogens are regulated due to their ability to permanently alter brain chemistry with repeated use. These substances have profound effects on neural circuits and behavior by manipulating neurotransmitters like dopamine and serotonin, impacting reward perception, energy levels, and mood regulation. Strict regulations are in place to prevent the harmful consequences of drug abuse.
What are the effects of drugs on behavior?
Drugs can have significant effects on behavior by altering communication between brain cells and manipulating neurotransmitters. Different drugs target specific neurotransmitters to either inhibit or excite neurons, affecting behaviors, emotions, and cognition. Illegal drugs like crystal meth, cocaine, and hallucinogens can lead to changes in neural circuits and behavior due to their impact on brain chemistry.
How do drugs alter brain function?
Drugs alter brain function by manipulating neurotransmitters in the brain. Different drugs like antidepressants, painkillers, and tranquilizers target specific neurotransmitters to change brain function and perception. Illegal drugs such as crystal meth, cocaine, and hallucinogens have potent effects on the brain by impacting reward perception, energy levels, and mood regulation through manipulation of neurotransmitters.
