UCLA ISAP has long histories of conducting drug abuse research and training in Los Angeles County and other parts of Southern California and throughout the country. The County and adjacent areas constitute a rich environment in which to conduct drug abuse research training, providing an ecological setting in which all permutations of drug abuse abound. The region has a publicly financed, centrally monitored system of treatment agencies and a multifaceted network of educational/research institutions with a large number of prominent scientists working in drug abuse research. Additionally, UCLA ISAP has some of the top investigators in the field of substance abuse. This affords us the opportunity to offer training experience to groups across the country, through presentations at conference as well as individually tailored trainings.
