The help of Dorothy C. and Leonard W. Whitney, Shirley M. Stelmack, and Miriam Winkeller was consistent and inestimable in preparing our section of this publication, and Miriam Winkeller's valuable assistance extended to the editing of this entire issue. Richard L. Rachin, Editor, Journal of Drug Issues was patient and supportive throughout, despite some trying difficulties and delays. The enterprise was made possible through the generosity of Standard Fittings Company.

Although this collection considers with care a wider range of drug-using patterns than is generally studied or even acknowledged, this information is in no way intended to condone, endorse, or encourage any use of any drug, licit or illicit. Rather this information is intended to be put in the service of the prevention of drug abuse.
