5. 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.

6. 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.

8. Examining the Externalities
Tobacco accounts for approximately $1 per pack in costs incurred by taxpayers and nonsmokers.
Medicare, Medicaid, Asthma,
Drunk Driving accounts for 40% of the 37,000 traffic accidents that cause 43,500 deaths
28% of all violent crimes (36% for rapes) are committed while the perpetrator is on drugs.
55% of inmates in jail, detention, or prison used drugs during the month leading up to their arrest.

9. 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.

10. A Twist on the Externalities Argument for Tobacco
Cigarette smokers are more likely to die
at an earlier age than they would have otherwise died.
in a less costly manner than they would have otherwise died. (e.g. heart attack rather than Alzheimer’s.)
Some economists estimate that this effect saves Social Security, Medicare and Medicaid (because they are not in nursing homes) more money than the $1 per pack in estimated external costs.

12. The Tobacco Settlement and why Elasticity Matters
1998 settlement between several states and several tobacco companies
$250 billion spread over 20 years
Demand for tobacco products is fairly inelastic. This means that the percentage change in prices will be more than the percentage reduction in smoking.

Implications
A dollar increase in the tax on cigarettes would reduce consumption by adults by 10% and reduce consumption by children by 25%.

15. The Importance of Elasticity for Drugs
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

17. Legalization with Taxes
Applying Figure 16.5 to drugs, legalization could deal with the external costs.
Making the tax too high would induce a black market.
