Vaporizing Marijuana vs Smoking Marijuana
A Look Inside: How Does A Vaporizer Work?
A vaporizer heats marijuana below the temperature at which it burns, so you inhale vapor instead of smoke; lab studies found less carbon monoxide and fewer combustion by-products, though vapor still carries risks. Lab studies of one common device used settings from 170 to 230°C (338 to 446°F). At these temperatures, the active ingredients are released as a vapor that is inhaled.
The Negative Effects Of Burning Marijuana
There is a real difference between what you inhale when you vaporize versus igniting your medical marijuana. A 2009 lab study found vapor made at 200 to 230°C held far more cannabinoids relative to by-products than cigarette smoke did.
Burning medical marijuana carries real risks. NIDA reports that cannabis smoke shares many toxins and carcinogens with tobacco smoke, and that long-term smoking is tied to chronic bronchitis. In a 2007 study of 18 healthy adults, vaporizing gave blood THC levels similar to smoking with less carbon monoxide, but it does not remove every risk.
Is Vaporizing Marijuana Safer? What Lab Studies Show
Safer in one respect, but not without risk: an earlier study found fewer combustion by-products in vapor than in smoke. When you vaporize medical marijuana, lab tests show electric vaporizers release roughly half to four fifths of the THC and CBD in the plant.
Vaporizing marijuana is meant to heat plant matter without igniting it, though one lab study found a gas-powered device did burn it. When you burn marijuana, you inhale smoke, which harms lung tissue.
It’s All About the Temperature
The same 2009 lab study found 170°C (338°F) gave the worst ratio of cannabinoids to by-products, while 200 and 230°C (392 and 446°F) gave better ratios than smoke. Device settings vary, so follow the maker’s instructions.
An old myth says that holding in smoke from a joint or bong increases the effects. A 1995 study of regular users found that holding smoke for 10 to 20 seconds raised blood THC but did not increase the high, while it kept smoke in the lungs longer.
So What Should You Look For In A Vaporizer For Marijuana?
Look for an electric vaporizer with a set temperature. In a 2016 lab test of five devices, the temperature-controlled electric models released THC and CBD without burning the plant, while a gas-powered one burned it. Avoid devices that cannot hold a steady temperature. Prices vary by model and change often, so compare current prices before you buy. Ask your physician whether inhaling fits your health and your certification.
