A.

The active ingredient in marijuana is THC. That's short for delta-9-tetrahydrocannabinol.

THC is rapidly absorbed after smoking pot. Within minutes, THC and the other substances in marijuana smoke cause short-term medical effects.

Signs of using marijuana include:

  • Rapid heart rate
  • Increased blood pressure
  • Increased rate of breathing
  • Red eyes
  • Dry mouth
  • Increased appetite, or "the munchies"
  • Slowed reaction time

These effects are reduced after three or four hours. However, marijuana hangs around in your system for as long as a month after smoking. The lingering effects mean you're impaired for several days to weeks after the high wears off.
