Arms

  • Experimental: Smart Talk Cannabis Awareness and Prevention
    At the start of Year 2, schools will be randomized in a 1:1 ratio to either receive 'Stanford REACH Lab's Smart Talk: Cannabis Prevention and Awareness' curriculum or 'delay-in-treatment (standard of care)'. Students in these schools will receive the Stanford curriculum designed as a 5-session course administered in a school class-room setting.
  • Experimental: Delay in Treatment Group
    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).
