Here are a few sentences to ponder, as we process the latest data on the overdose crisis:

Most drug epidemics don’t simply disappear: they transform themselves into something else. For example, periods of excessive stimulant use are often followed by periods of rising alcohol, sedative and opiate use. There are drug-facilitated cycles of stimulation, introspection, intoxication, and emotional anesthesia. Repeated episodes of each drug experience generate the appetite for the next experience/drug in the sequence. In the second half of the twentieth century, we have seen two repetitions of the following cycle: short acting stimulant use (cocaine) followed by longer acting stimulant use (methamphetamine) followed by a rise in depressant use (alcohol/sedatives/heroin). While this cyclical pattern of stimulation, over stimulation, self-sedation is evident in individuals, it is equally evident in the evolving drug tastes of the larger society. The implication is that a community plagued by rampant methamphetamine dependence must respond not only to this pattern, but to the rising problems of alcohol, sedative and narcotic dependence that are likely to follow it.
