A new study published in the Journal of Analytical Toxicology, and published online by the National Institute of Health, gives us the clearest answer to date on how long cannabis edibles stay actives after they’ve been made.
“Presented is a method for the preparation and application of THC and CBD containing brownies used as quality control (QC) material for the analysis of marijuana or cannabinoid baked medibles”, states the study’s abstract. “It was determined that the process used to prepare and bake the brownie control material did not degrade the THC or CBD. The brownie matrix was found not to interfere with the analysis of a THC or a CBD.”
For the study, “ten commercially available brownie matrixes were evaluated for potential interferences”. According to researchers “none of them were found to interfere with the analysis of THC or CBD. The laboratory baked medible QC material was found to be stable at room temperature for at least 3 months.”
