Biologic Risk Factors for Substance Misuse
Genetics: Children of alcoholic parents are at higher risk for developing alcoholism and drug dependence than are children of nonalcoholic parents
- Increased risk is partly the result of environmental factors, but evidence points to the importance of genetic factors as well
- Adoption studies have shown higher rates of alcoholism in sons of biologic fathers with alcoholism than in those of nonalcoholic biologic fathers
->These studies led theorists to describe the genetic component of alcoholism as a genetic vulnerability that is then influenced by various social and environmental factors
Brain’s Reward Center Theory: Addictive substances or behaviors affect the brain’s reward system by flooding the nucleus accumbens with dopamine
- Repeated exposure causes nerve cells in the nucleus accumbens and prefrontal cortex to couple liking something with wanting it
- This motivates someone to seek the pleasure source

PTSD
Mood disorders
Anxiety disorders
Abuse
Neglect
Poverty
Lack of parental involvement
Experimentation

Home environment that promotes substance abuse

Designer Drugs
AKA Club Drugs
Synthetic substances made by altering existing medications or formulating new ones not yet controlled by the FDA
- Amphetamine-like effects, some also have hallucinogenic effects
As attempts to make such drugs illegal are formulated, makers of the drugs alter the substance slightly so it once again falls outside the law.
They may also contain unknown compounds as a filler or additive, and the effects are unknown until the drug is ingested.
Some of these substances are known by generic terms such as bath salts or plant food, although the substances are never used for those purposes.
- Others have specific names, such as ecstasy (methylenedioxymethamphetamine), special K (Ketamine), or smiles (2C-1)
Intoxication
