Drugs are a species of property, and hence the right to drugs is a form of property right. Accordingly, I maintain that we have a right to grow, buy, and ingest drugs much as we have a right to grow, buy, and ingest food; and that drug prohibition, epitomized by our prescription laws, constitute deprivations of our fundamental right to own and use property.Thomas Szasz Friedman & Szasz on Liberty and Drugs, The Drug Policy Foundation Press, 1992
