People use drugs, legal and illegal, because their lives are intolerably painful or dull. They hate their work and find no rest in their leisure. They are estranged from their families and their neighbors. It should tell us something that in healthy societies drug use is celcbrative, convivial and occasional, whereas among us, it is lonely, shameful, and addictive. We need drugs, apparently, because we have lost each other.
