AbstractThe newly proposed framework for non-addictive psychoactive substances postulated by Müller & Schumann (M&S) provides an interesting and plausible explanation for non-addictive drug use. However, with specific reference to the relevant behavioral addiction literature, this commentary argues that the model may unexpectedly hold utility not only for non-addictive use of drugs, but also for non-addictive use of other potentially addictive behaviors.
