What percentage of THC is consumed when marijuana is eaten?

essentially, more than 100%. when cannabis [don't use the term "marijuana", it was a rarely used Mexican slang term that was proliferated to stir up racist sentiment and help the criminalization in the mid thirties] is eaten, the liver converts the THC into it's 11-hydroxy-THC form, which is about 3 times as potent, but much slower acting, than the standard, smoked THC which almost immediately travels to the brain via capillary action mostly in the lungs. the 11-hydro-THC is carried from the liver to the brain via the blood stream.

studies are varied, but when smoked, you get between 20 and 70% of the THC content. however, it is not converted by the liver to a more potent form.

Be Safe! Don't Smoke! Vape or eat, smoke inhalation kills.
