When the drugs are not active in the brain, dopamine levels can drop, causing uncomfortable withdrawal symptoms and powerful cravings. This is a list of dopaminergic drugs. Studies have shown that repeated drug use could alter the thresholds required for dopamine cell activation and signalling. The reinforcing effects of drugs are associated with significant and fast increases in extracellular dopamine, which mimic those induced by physiological dopamine cell firing but are more intense and protracted.The increase in knowledge has led to more complex models of drug addiction. Dopamine is a type of neurotransmitter that has several important functions in the brain and body. It binds to receptors in the brain, making them send signals from one cell to another..
