Dissociation Theory Theory by Ernest Hilgard. is.com/hilgard.htm is.com/hilgard.htm We voluntarily divide our consciousness up. Ice Water Experiment. We have a hidden observer, a level of us that is always aware.

Drugs

Our brain is protected by a layer of capillaries called the blood-brain barrier. The drugs that are small enough to pass through are called psychoactive drugs.

Drugs are either…. Agonists Antagonists Reuptake inhibitors If a drug is used often, a tolerance is created for the drug. Thus you need more of the drug to feel the same effect. If you stop using a drug you can develop withdrawal symptoms.

Stimulants Speed up body processes. More powerful ones (like cocaine) give people feelings of invincibility.

Depressants Slows down body processes. Alcohol Anxiolytics (barbiturates and tranquilizers)

Alcohol More than 86 billion dollars are spent annually on alcoholic beverages. Alcohol is involved in 60% of ALL crimes. Alcohol is involved in over 70% of sexually related crimes. Is it worth the cost?

Hallucinogens Psychedelics Causes changes in perceptions of reality LSD, peyote, psilocybin mushrooms and marijuana. Reverse tolerance or synergistic effect

Opiates Has depressive and hallucinogenic qualities. Agonist for endorphins. Derived from poppy plant. Morphine, heroin, methadone and codeine. All these drugs cross the placental barrier….teratogens.
