How is marijuana used?

There are a few different ways people use marijuana:

  • smoking hand-rolled cigarettes called joints or marijuana cigars called blunts (often made by slicing open cigars and replacing some or all of the tobacco with marijuana)
  • inhaling smoke using glass pipes or water pipes called bongs
  • inhaling vapor using devices that pull the active ingredients (including THC) from the marijuana into the vapor. Some vaporizers use a marijuana liquid extract. 
  • drinking tea brewed with marijuana or eating food with marijuana cooked into it, sometimes called edibles—such as brownies, cookies, or candy.

These extracts made from the marijuana plant should not be confused with “synthetic marijuana,” sometimes called “K2,” “Spice,” or “herbal incense.” These synthetic drugs are laboratory-made chemicals similar to THC that are sprayed onto plant materials to make it look like marijuana, but are often much stronger and very dangerous. Unlike marijuana, their use sometimes directly results in overdose deaths. Learn more about "synthetic marijuana”.
