Dalrymple points out that drugs,
far from being expanders of consciousness, severely limit it. One of the characteristics of drug-takers is their intense and tedious self-absorption; their journeys into inner space are forays into inner vacuums. Drug-taking is a lazy man’s way of pursuing happiness and wisdom, and the shortcut turns out to be the deadest of dead ends.
Use of narcotics
has the effect of reducing men’s freedom by circumscribing the range of their interests. It impairs their ability to pursue more important human aims, such as raising a family and fulfilling civic obligations. Very often it impairs their ability to pursue gainful employment and promotes parasitism.
