Document Summary

Ethanol: the legal drug that is heavily marketed and more prevalent than nicotine. General effects of ethanol: it is a general cns depressant, meaning that it does not specifically act in one region of the brain, it can act everywhere depending on the dosage. As you increase the dose, the effect of ethanol becomes more widespread. As the concentration in the blood increases, the effects of ethanol intensify: you go from talkative sedation sleep anesthetic coma death. *when taking lower doses of ethanol, you"ll find that people tend to be more talkative rather than depressed" and this is because inhibition is tended to individuals are talkative as a result of depression inhibition. If drinking at higher doses, there"s going to be impaired motor function and possible death. Early phases of alcohol consumption: when you"re the life of the party. As a result, ethanol can cause delusions and (past a certain drinking point) cause amnesia.
