Marijuana is legal in Washington State for adults 21 and over, but it does pose potential health risks. The safety of marijuana, or cannabis, has not been established, and more research is still needed. However, the research that has been done shows that marijuana can have have both short-term and long-term effects on health. Tetrahydrocannabinol (THC) is the psychoactive chemical in marijuana. Many marijuana products today have much higher THC levels than in the past.

Short-term effects of marijuana:

  • Drowsiness
  • Loss of inhibitions
  • Decreased coordination
  • Anxiety and/or paranoia
