There is conclusive evidence that marijuana use, particularly in early adolescence, can affect brain development. Most of the effect is on memory, attention, and executive function. How do we prevent these negative effects? Dr. Cermak's advice is: delay, delay, delay. The more success we have getting kids to delay onset of use, the more protection we provide.
