Many psychoactive drugs trigger activity along a pathway of cells in the brain called the “reward pathway.”

The “Reward Pathway”

Brain cells along the activated reward pathway release a chemical called dopamine (DOH puh meen).

The extra dopamine released during drug use can cause the user to ignore the harmful effects of the drug and want to continue using it.

Flooding the reward pathway with dopamine may lead to intense cravings for the drug.

After a time, drug abuse can dull the brain’s reactions to natural levels of dopamine.
