“…Marijuana use is associated with lower academic performance and higher rates of truancy and drop-out among high school students, whereas its impact on academic performance among older users seeking higher education is less certain (Cox, Zhang, Johnson, & Bender, 2007;Fergusson, Horwood, & Beautrais, 2003;Lynskey, Coffey, Degenhardt, Carlin, & Patton, 2003). Although it can be assumed that marijuana use exists in graduate school settings, given the high rates of reported use among undergraduates, relatively few studies have addressed marijuana use among this specific population (Boniatti et al, 2007;Lipp, Benson, & Taintor, 1971;Schaps & Sanders, 1970;Seiden, Tomlinson, & O'Carroll, 1975).…”
