An ongoing policy debate concerns whether to legalize the use of drugs such as marijuana and cocaine. Some researchers estimate that legalizing cocaine would cause prices to fall by as much as 95%. Proponents of legalization argue that legalizing the drug use would lower crime rates by eliminating the main reason for the murderous gang wars that plague many big cities and by reducing the incentive for drug addicts to commit robberies and burglaries. Opponents of legalization argue that lower drug prices would lead more people to use drugs. What do you think? How can price elasticity help?
