A study by the National Institute on Drug Abuse found that "[m]arijuana use makes tobacco use more pleasurable and may increase the user’s risk for becoming addicted to nicotine." Experiments involving rats found that those animals exposed to THC, the psychoactive ingredient in marijuana, self-administered nicotine at higher rates than rats with no such exposure. This connection raises concern that pot may be a "gateway" drug to nicotine.
