| Delay in Treatment Group | Experimental | At the start of Year 2, schools randomized to the delay-in-treatment group will receive a standard of care for one year. After year 2, the delay-in-treatment group will crossover to receive 'Stanford REACH Lab's Healthy Futures: Cannabis Prevention and Awareness until year 5 (receive intervention for years 2 to 4).
