Marijuana can have wide-ranging effects

Marijuana can have wide-ranging effects, such as short-term memory loss and increased heart rate.

THC, the active ingredient in marijuana, “hijacks and corrupts” the natural process of endocannabinoids, a key family of chemicals that help guide the brain in proper maturation, says Ruben Baler, a neuroscientist with the National Institute on Drug Abuse (NIDA). These chemicals “play key roles in memory formation, learning, decision-making,” says Baler.
