The following is a quick overview of the most common neurotransmitters and how drugs affect them. This information is from Drugs and Society, 11th edition, by Glen Hanson and Peter Venturelli, 2012.
| Neurotransmitters | Type of Effect | Major CNSChanges | Drugs | Influence |
|---|---|---|---|---|
| Dopamine | InhibitoryExcitatory | Euphoria, Agitation, Paranoia | Amphetamines and Cocaine | Activates the Neurotransmitters |
| GABA | Inhibitory | Sedation, Relaxation, Drowsiness, and Depression | Alcohol, Valium type, and Barbiturates | Activates the Neurotransmitters |
| Serotonin | Inhibitory | Sedation, Relaxation, and Sleep | LSD | Activates the Neurotransmitters |
| Acetylcholine | InhibitoryExcitatory | Excitation, Mild Euphoria, and Insomnia | Tobacco and Nicotine | Stimulates the Neurotransmitters |
| Endorphins | Inhibitory | Blocks Pain, Mild Euphoria, and Slow Respiration | Narcotics | Activates the Neurotransmitters |
Look at how these neurotransmitters affect the Central Nervous System: evoking euphoria, sedation, and relaxation, as well as blocking pain. These are no small incentives for people.
