Synthetic THC, also known as fake marijuana, is used by college students in the United States. The present study examined reasons for recent synthetic THC use among college students (N = 339). Students completed a 3-page survey during regularly scheduled class times. Results indicated students reported using synthetic THC for curiosity, to get high, and the fun of feeling high. No significant differences in reasons for use were found based on sex and grade. College students reported most often obtaining synthetic THC from head shops. Study findings may be beneficial to college health professionals and others working with college students. High rates of lifetime use may suggest that educational and intervention programs are needed.
