“…Recent pilot studies have assessed the efficacy of exercise, a structured and planned form of physical activity, interventions in addressing drug (Brown, et al, 2010), marijuana (Buchowski, et al, 2011), and alcohol (Brown, et al, 2009) misuse, with positive results (Weinstock, Barry, & Petry, 2008). However, to our knowledge only one study has assessed activity level and motivation to exercise in MMT patients; they found low levels of physical activity in MMT participants, but encouragingly, motivation to exercise was the best predictor of physical activity (Pieper, Templin, Kirsner, & Birk, 2010). Understanding benefits and barriers to exercise as well as level of physical activity in a MMT population may be important to motivate this group to increase physical activity.…”
