New research looking at the effect of gamma irradiation on dried cannabis is published in the Journal: Frontiers in Ethnopharmacology.

“Evaluating the effects of gamma-irradiation for decontamination of medicinal cannabis” looked at 4 separate strains of cannabis produced by Bedrocan BV in the Netherlands and tested samples before and after the irradiation process to test for changes in cannabinoids, terpenes and moisture content.

The results of the peer reviewed research showed no change in THC, CBD or moisture content, and minimal damage to a few terpenes present on the cannabis. While only a few terpenes were diminished, the exact ratio of terpenes in a strain is moderately changed. The overall profile is still clearly recognizable between the different varieties tested. The samples were compared before and immediately after standard gamma-irradiation treatment, and then evaluated visually and with GC and HPLC analysis methods.
