What are the Severity ratings based on # of symptoms?
Mild= 2-3
Moderate= 4 to 5
Severe= 6 or more
What are the 5 General Categories?
- Depressants (alcohol, sedative hypnotic, anxioylic)
- Stimulants (cocaine, amphetamines, caffeine, tabacco)
- Opioids (heroin, opium, oxy)
- Hallucinogens (cannabis)
- Other (inhalants, steroids, ketamine)
Tolerance
reduction in the effect of a drug as a result of repeated use requires greater quantities to achieve the same effect
Withdrawal
negative physical and psychological effects occur when stopping taking or reducing substance amount
What are the Levels of Substance Involvement?
Use, Intoxication, Abuse, Dependence/Addiction
Physiological Dependence
experience tolerance and withdrawal
What are Depressants
behavioral sedation and can induce relaxation
Examples of Depressants?
Alcohol, sedative, hypnotic and anxiolytic drugs
What occurs in the body with an Increase in Tolerance?
Changes in liver enzymes: efficient metabolism
CNS: changes in the number and sensitivity of GABA and glutamate receptors
What is GABA?
neurotransmitter that blocks impulses between nerve cells in the brain.
What is the function of Glutamate receptors?
mediate fast excitatory synaptic transmission in the central nervous system
What are some Withdrawal Symptoms?

What are the Short Term Alcohol effects on Neurotransmitters?
GABA: increased; may reduce tension /anxiety
Serotonin: increased; pleasurable effects and cravings
Dopamine: increased; pleasurable effects
Glutamate: inhibited; slurred speech and memory loss
What are the Long Term effects of Alcohol?
Severe malnutrition, B vitamin deficiency (Korsakoff’s liver syndrome), damaged endocrine glands and pancreas, heart failure, hypertension, reduces immune function (cancer)

What are examples of stimulants?
cocaine, caffeine, amphetamines
How do stimulants effect us?
