How do drugs affect you?
● Affect psych state
○ Desired effect
■ Disrupts cognition, affects mood, affects activity, etc.
● Affect physio state
○ Change in state of homeostasis
■ Affect cns, create proteins, etc.
● Ultimate price to pay is when drug has toxic effects
○ Long term changes in physio or psych state
Drug dosage issues?
● Frequency of drug intake
○ Acute → over time small amounts of drug
○ Chronic
■ Behavioral effects of a drug
■ Ongoing effects
● Tolerance
● Sensitization → impact of homeostasis
○ Chronic use results in external cues (time of day, setting)
prepare body of alcohol (enzymes, liver, proteins, etc.) so
when in a different setting without cues, body is not
prepared for the alcohol → more dramatic effects
■ Drug dependence
● Need the drug to function
○ Drug toxicity: acute or chronic use can result in drug toxicity
■ Acute → short term effect that is physio → alcohol poisoning
Drug Toxicity
● Acute → occurs after an initial exposure
● Chronic → occurs when there is toxicity after repeated exposure to a drug
Examples of acute toxicity
● Accidental lethal overdose of heroin
● Behavioral dangers from being “high”
● Dangerous combinations of alcohol with any drug
● Dangerous combination of alcohol with any drug
● Overmedication of prescription of OTC drugs
Examples of chronic toxicity → vital organs damaged frequently
● Liver disease due to chronic alcoholic consumption
● Lung cancer due to chronic tobacco smoking
● Cardiovascular disease due to chronic tobacco smoking
● Pulmonary disease due to chronic tobacco smoking
Document Summary
Disrupts cognition, affects mood, affects activity, etc. Ultimate price to pay is when drug has toxic effects. Long term changes in physio or psych state. Acute over time small amounts of drug. Chronic use results in external cues (time of day, setting) prepare body of alcohol (enzymes, liver, proteins, etc. ) so when in a different setting without cues, body is not prepared for the alcohol more dramatic effects. Drug toxicity: acute or chronic use can result in drug toxicity. Acute short term effect that is physio alcohol poisoning. Acute occurs after an initial exposure. Chronic occurs when there is toxicity after repeated exposure to a drug. Dangerous combinations of alcohol with any drug. Dangerous combination of alcohol with any drug. Examples of chronic toxicity vital organs damaged frequently. Liver disease due to chronic alcoholic consumption. Lung cancer due to chronic tobacco smoking. Cardiovascular disease due to chronic tobacco smoking. Pulmonary disease due to chronic tobacco smoking.
