Experts Urge 80% of Cannabis Users to Switch From Smoking to 5 Safer Methods

1 articles · Updated · The Washington Post · Jul 3

Summary

  • Nearly 80% of medical cannabis users still smoke it, but physicians Peter Grinspoon and David Kroll say tinctures, edibles, capsules, topicals and suppositories are safer options.
  • Smoking exposes users to combustion toxins and carcinogens, while vaping can damage lungs through degraded compounds and contaminated THC oils; the 2019 EVALI outbreak caused 2,807 hospitalizations and 68 deaths by 2020.
  • Tinctures rank highest for controllable dosing and faster onset—about 15 minutes—while edibles take 1 to 3 hours but can last 6 to 12 hours, making them useful for steady symptom control.
  • Capsules may reduce overuse because they are not flavored like gummies, and topicals or suppositories can deliver localized relief with less psychoactive effect.
  • More than a quarter of adults in the U.S. and Canada use cannabis medically, and the experts say patients should treat the product like a drug delivery device and use the lowest effective dose.
