Psychoactive drugs typically create a pleasurable feeling that the

PATHWAY ” of the brain. Brain cells along this pathway release a
chemical called DOPAMINE. Dopamine is not necessarily a
dangerous chemical but can be in association with drug use.


The extra dopamine released during the 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

After a time, drug abuse can dull the brain’s reactions to natural levels of
dopamine. The user no longer feels pleasure from normal activities.
