Dust Off or Canned Air is sold in office supply stores. Its intended use is to clean dust out of keyboards. But it does a much better job of clearing out your mind if you place the nozzle in your mouth and inhale the toxic air. Hold the fumes in and exhale as the world starts to go Wah Wah Wah. Make sure to hold the can right side up so you don't freeze your tongue off. This is the devil's drug never do it. It is highly addictive and highly brain damaging.
