Abstract
One hundred homeless adolescents were interviewed in 1971 when they still were active drug abusers. The same group was followed‐up 3 years later in 1974 with personal interviews. All were traced, with the exception of three individuals residing in foreign countries and four who had died. At follow‐up one third were abstinent and were well adapted socially, one third showed an uncertain social adaptation, and one third were still addicted and had a poor social adaptation. The various factors responsible for their psycho‐social development and relation to drug abuse are discussed.
