Document Summary

Lecture 7: mechanisms of drug actions, psychopharmacology of neural stimulants. Everyone has different views on what drugs one should or shouldn"t take (good vs. bad) What is legal in one country, may not be legal in others; same as at different times within a country (eg. smoking in public places) If a drug is taken repeatedly, most drugs show a decreasing behavioural effect. More you take it, the less effect that it has. If you have been taking a drug for a long period of time, and then suddenly stop taking it, will have a craving for the drug. Behavioural affect of withdrawl is almost the exact opposite of the behavioural effect of the drug itself (due to the compensation of tolerance) Never take people off depressants (alcoholics included) because run risk of having seizures and dying. Substitute the alcohol with another depressant that doesn"t have all the behavioural affects of alcohol, and then slowly wean them off the drug.
