Executive Summary

The first paper in the series deals with the potency of various cannabis products on the Irish market, in terms of its content of the main psychoactive component THC (short for Tetrahydrocannabinol). The NACD hopes to update the data in this report on a regular basis given the increasing international concern about rising THC levels particularly in herbal cannabis of the “Skunk” or “Weed” variety. Allied to the increased levels of THC in these varieties is the absence of a second key chemical called CBD which seems to block some of the effects of THC on the brain.
