International Narcotics Control Board
Modafinil is classified by the United States FDA as a schedule IV controlled substance, a category for drugs with valid medical uses and low addiction potential. The International Narcotics Control Board does not consider modafinil as a narcotic nor a psychotropic substance . In fact, modafinil may increase abstinence rates in a subgroup of cocaine addicts while modafinil-related discontinuation adverse effects are no different from placebo. Modafinil also attenuates drug-seeking in methamphetamine-conditioned rats.
