There is no standard dose. Start with the lowest label dose. Wait at least 2 hours before you judge the effect. Do not add a second patch on the first day.

Onset and peak

Labels list onset at 15 to 60 minutes. Peak effect is 1 to 4 hours. Human pharmacokinetic data on cannabis patches are limited. Absorption depends on skin site, skin temperature, and product formulation.

Use steps

  1. Read the label for dose and wear time.
  2. Apply to clean, dry, intact skin. Use a site with little hair.
  3. Press the patch for 10 seconds.
  4. Do not cut the patch.
  5. Do not apply heat over the patch. Heat can raise absorption.
  6. Rotate sites between patches.
  7. Remove at the label time. Fold the patch sticky sides together and discard it out of reach of children and pets.

Limits and risks

THC can cause dry mouth, fast heart rate, anxiety, and impaired coordination. Do not drive or operate machinery after a new THC patch until you know the effect. Do not use a patch if you are pregnant or breastfeeding without medical advice. Keep patches away from children and pets.
