From the Lawrence Daily Journal-World for April 4, 1972:
Dr. Margaret Haggan, a physician at Kansas University's health service and a member of the Mayor's Commission on Drugs, had recently assessed drug use in Lawrence, and the news was not positive. Drug abuse, Dr. Haggan said, had "improved at the university, but it's worse in the high school and junior highs -- it's part of a nationwide shift.... Marijuana -- this is where a lot of the kids start -- is definitely in the junior high. By high school, more of the kids are on acid, barbiturates and amphetamines." Ric Silber, director of Headquarters, estimated that "certainly a majority" of Lawrence High School students had at least tried marijuana, but from his perspective, regular pot smokers were in the minority.
