In June 2000, Canada replaced the black-and-white warning messages on cigarette cartons sold in that country with color graphic depictions of the consequences of smoking, mandating that they cover 50% of the front surface of each carton. Each tobacco product features one such image from a series, which includes people dying in hospitals, rotting mouths, and dissected body parts depicting tumors, along with simple bold messages stating that cigarettes cause cancer, mouth disease, impotence, and harm babies.
Other examples of demand reduction programs include D.A.R.E., the State of Montana's Not Even Once., and the Drug policy of Sweden.
Economists such as Milton Friedman agree that, due to the law of supply and demand, reducing demand is the only effective way to reduce drug use long-term. It is questionable, however, whether the programs pursued under the name of demand reduction actually reduce demand.
