James A. Inciardi was a major proponent of the United States' **War on Drugs**.

In numerous books and essays, Inciardi argued for causal links between marijuana and HIV/AIDS, marijuana and violent murder, marijuana and homosexuality (and reverse), marijuana (but not tobacco) and lung cancer, homosexuality and pedophilia, not being white and criminality, and being female and suffering from cognitive impairment.

Despite being wrong almost without exception, he was appointed co-director of the Center for Drug and Alcohol Studies at the University of Delaware and professor of sociology and criminal justice.
