Affect of Drugs on the Brain
• The quicker the drug reaches the brain, the
more likely the user is to become addicted.
• Drugs work in the brain by tapping into its
communication system and interfering with
the way nerve cells normally send, receive,
and process information.
The Brain and Drugs
• Once a drug reaches the brain, it acts on one
or more neurotransmitters, either increasing
or decreasing their concentration and actions.
The Brain and Drugs
• Neurotransmitters include substances such as
serotonin and dopamine that are released to
make you feel good.

substance/drug
• Addiction: Habitual (regular) and out of control use of drug or substance;
user is dependent on substance/drug
• Withdrawal: Changes that occur when substance/drug use stops
Rate of Addiction
• Genetics: connection to addiction via a family
member or relative

cause addiction even after just one use!
