WHAT IS ADDICTION? But what is addiction? We now know that while the initial decision to use drugs is voluntary, drug addiction is a disease of the brain that compels a person to continue taking drugs despite their many adverse health and life consequences.

The 5 C’s & a “D” Chronicity Compulsive use
Inability to Control use Continued use despite consequences Cravings Chronicity Denial
10
Addiction is a Chronic Brain Disease
Not a lack of will power or poor judgment or bad behavior or bad choices Impaired control - caused by brain chemistry malfunction DRUG USE PRODUCES BRAIN DAMAGE!
11
Neurotransmitter Mediated
(Not under conscious control) CHRONIC, PROGRESSIVE, POTENTIALLY FATAL DISORDER

in Fundamental and Lasting Ways
Addiction is a Brain Disease Prolonged Use Changes the Brain in Fundamental and Lasting Ways FACULTY NOTE: (from NIDA teaching instructions – you may use this narrative text as a guide, but it does not need to be repeated word for word) Positron emission tomography (PET) scan of a person on cocaine Cocaine has other actions in the brain in addition to activating reward. Scientists can now see how cocaine actually affects brain function in people. The PET scan allows us to see how the brain uses glucose; glucose provides energy to each neuron so it can perform work. The scans show where the cocaine interferes with the brain's use of glucose - or its metabolic activity. The left scan is taken from a normal, awake person. The red color shows the highest level of glucose utilization (yellow represents less utilization and blue shows the least). The right scan is taken from a cocaine abuser on cocaine. It shows that the brain cannot use glucose nearly as effectively – point out the loss of red compared to the left scan. There are many areas of the brain that have reduced metabolic activity. The continued reduction in the neurons' ability to use glucose (energy) results in disruption of many brain functions.

“FEEL GOOD” NEUROTRANSMITTERS
Endorphins Nor-epinephrine Phenylethylmine Dopamine

PHENYLETHYLMINE FEELINGS OF BLISS FEELINGS OF INFATUATION CHOCOLATES
31
INHIBITORY NEUROTRANSMITTERS
ENKEPHALINS GABA (Gamma Amino Butyric Acid)
32
GABA Gamma Amino Butyric Acid ANTI-STRESS ANTI-ANXIETY ANTI-PANIC
ANTI-PAIN FEEL CALM MAINTAIN CONTROL FOCUS
33
GABA = Calming “THE BRAKES” Primary brain inhibitor necessary to feel calm & relaxed
34
GLUTAMATE Brains primary excitatory neurotransmitter
Important in memory
35
HORMONAL NEUROTRANSMITTERS
36
SEROTONIN Neurotransmitter responsible for regulating moods and emotions A lack of serotonin can lead to depression and /or obsessive, compulsive behaviors
