Many young adults remember their childhood participation in Drug Abuse Resistance Education, better known by the acronym D.A.R.E. One of the program's core messages is that marijuana is a "gateway" to all sorts of other substances. D.A.R.E's effectiveness was later called into question, and its curriculum overhauled, but the legend remains.
