How many hours does the effects of marijuana last?

Answer 1

The best way to get the drug out of your system after smoking marijuana is to drink plenty of water and sweat as much as possible. Wait. Time passes and the high wears off naturally. You DO NOT want to take other chemicals to offset the marijuana. {And if you don't have the time, you shouldn't have been smoking grass, or been in the room where others where smoking.}

Answer 2

There may be only one way. Wait until it wears off. That is the disadvantages of this drug. It takes time to wear off.

Take a benzo like Valium or Xanax. That never fails to bring me right down if my high is too intense.

Answer 3

Answer 4
