5 is the new 10 Feds standard dose of THC when testing cannabis products for 5 mg of THC
A standard dose makes it easier to analyze THC-related cannabis studies, which are a top priority for both NIDA and the National Advisory Council on Drug Abuse. “The intention of this announcement is not to prescribe the amount of THC that is permitted for use in research projects. In fact, researchers are free to use more or less than 5 mg of THC as needed for their study. However, for applicable studies, investigators must report the amount of THC using the standard unit. The investigators can also specify the amount of THC in other units (e.g. milligrams), ”the message says.
