Short Answer

Cannabis odor comes from volatile compounds such as terpenes and sulfur-containing molecules that leave the plant and travel through the air. Get the flower into an airtight container, pull room air outside with a fan or a carbon filter, and capture smoke and vapor at the source. Cover scents add a second smell on top of the first one, so removal beats masking.

Before You Start

Seal the Flower

  1. Take the flower out of the plastic bag or original packaging, since those bags leak odor.
  2. Move the flower into a glass jar and fill it so little air space remains.
  3. Wipe the rim and threads of the jar with a dry paper towel to remove loose plant material and resin.
  4. Close the lid and press or clamp it until the gasket seats.
  5. Place the jar inside a second container, such as a vacuum-sealed bag or a smell-proof pouch.
  6. Store the container in a cool, dark spot below 77 F (25 C), since heat pushes volatile compounds out of the plant.
  7. Open the jar only with the window open and the fan or purifier running.

Move the Air

  1. Open the window a few inches and keep the room door closed.
  2. Set a box fan in the window facing out so it pushes room air outside instead of pulling outdoor air in.
  3. Run an air purifier with an activated carbon filter, not a HEPA-only unit, because carbon adsorbs odor molecules while HEPA captures particles.
  4. Replace the carbon filter on the schedule the maker lists, since a loaded filter stops working.
  5. Keep the door to the rest of the home shut while any flower is open.

Handle Smoke and Vapor

  1. Smoke or vape near an open window with the fan running, or step outside.
  2. Exhale through a sploof packed with activated carbon.
  3. Drop roaches, ash, and resin into a small sealed jar instead of an open ashtray.
  4. Empty that jar into a sealed bag and take the bag out of the room at the end of the day.
  5. Wipe fingers, lighters, trays, and phone screens with isopropyl alcohol after a session, since resin transfers odor to surfaces that keep releasing it.
