A decline in supervision is not the entire story. Even in the fifties there were undersupervised children . . . who nevertheless did not become pregnant at thirteen . . . and who did not smoke anything stronger than an occasional Camel or Lucky Strike. . . . It took a combination of unsupervised children and a permissive, highly charged sexual atmosphere and an influx of easily acquired drugs and the wherewithal to buy them to bring about precocious experimentation by young and younger children. This occurred in the mid-seventies.
