The Importance of Elasticity • If people are addicted to a particular drug, their demand for it will be inelastic. • Drug interdiction efforts shift the supply curve to the left. • This will cause prices to rise – Addicts will not reduce quantity demanded much – Recreational users will reduce quantity demanded more McGrawHill/Irwin © 2002 The McGrawHill Companies, Inc., All Rights Reserved.
Arguments for Making a Good Illegal • People have limited information about the good, are not capable of making a good decision about the good or the good is addictive and one-time users can not learn from their mistake. • There are externalities, effects of a transaction that hurt or help people who are not a part of that transaction, involved in the production or consumption of the good. • The good is immoral.

Preventing Bad Decisions • Economists are typically reluctant to assume that people can not make good decisions. • Drugs tend to be an exception to this rule because they are addictive. McGrawHill/Irwin © 2002 The McGrawHill Companies, Inc., All Rights Reserved.

Examining the Externalities • 30% of all violent crimes (38% for rapes) are committed while the perpetrator is on drugs. • 80% of inmates in jail, detention, or prison used drugs during the month leading up to their arrest. • there are nearly 23,000 drug-related homicides every year.

Battling Negative Externalities While Creating Others • Much of the drug violence that exists, only exists because of laws criminalizing drug use. • If cocaine, methamphetamine, and marijuana were legal and inexpensive, – there would be less of a need for addicts to rob in order to get money to buy them. – there would be no drive-by shootings to protect turf.
