Document Summary

For millennials drugs have always been used to alter consciousness. Used mostly recreationally to change our normal state. Drugs alter consciousness by disrupting fragile balance of neuronal molecules that permit. This manifests as a change in synaptic transmission. Example: a tiny grain of lsd has huge effects on the body. Act on neurotransmitter system: increase or decrease amount. Act on receptor system: drugs can bind to receptor or block receptor. Whe is ac neur releas and attac rece. When presynaptic cell is activated neurotransmitters are released into synapse and therefore attaches on to receptor. Continued use of a drug can induce physiological changes that influence drug efficacy. Tolerance = decreased responsivity to a drug in an attempt to maintain homeostasis. Withdrawal = results from compensatory responses that are engaged to maintain homeostasis. Your body has an "anti drug" system in place called the "compensatory response syst.
