Toxic = poisonous, deadly, or dangerous
What makes a drug toxic?
Amount used
How it is used
What the user did while on the drug
Physiological toxicity & behavioral toxicity
Acute effects & chronic effects

4. Drug-Related Toxicity
Examples of acute toxicity

increases the danger to themselves and others
• Physiological: Overdose that causes the user to stop breathing
Examples of chronic toxicity

5. Toxicity & DAWN
A system for collecting data on drug-related deaths and
emergency room visits at some U.S. metropolitan
hospitals
DAWN collects data on improper use of legal prescription
and over-the-counter drugs as well as illicit drugs
What it tells us about how dangerous a drug is - Simply
gives us total deaths/ER visits
What it does not tell us about how dangerous a drug is
Consider relative danger vs. total impact of the drug
Number of users vs. number of reported problems
Alcohol is reported only in combination with other drugs
Drug-alcohol and drug-drug combinations are very
common

8. Drugs & Crime: Why We Regulate Drugs
We want to protect society from the dangers of some types of drug use
What are the real costs to a society?
Some laws are not developed as part of a rationally devised plan and may not be
realistic or effective
Based on 4 ideas of drugs and crime:
1. Drug use changes personality; creates “criminal type”
2. People under the influence may commit crimes (e.g., many cases of
homicide, domestic violence, etc.)
3. Crimes may be carried out to obtain money for drugs
4. Drug use is a crime
