Dronabinol Interactions With Cognitive Enhancing Drug in Humans

Marijuana use is a major problem among veterans and non-veterans. A patient's use of marijuana while engaged in psychotherapy treatment may affect their memory and, therefore, limit their ability to benefit from treatment. This study is designed to test a new pharmacotherapy, modafinil, which has the potential to improve memory functioning in marijuana using individuals. We hypothesize that modafinil treatment will decrease ratings of drug liking and improve cognitive measures, especially episodic memory.
