WORLD (Agencies) A scientific team at the National Health Institute in Bethesda, Maryland (USA), has opened the doors to creating a variety of cannabis for medical use that removes its halucinogenic properties but retains those that are anaelgesic. The team published its findings in Nature Chemical Biology, a digital magazine, describing how they attained it by modifying its components, thus reducing its side effects. Use of cannabis as medication -as well as long term use as a 'recreational' drug- has been shown to have a deteriorating psychomotor effect, and therefore limits its development as an anaelgesic for clinical use. The psychoactive effects of marihuana are determined by their active component, tetrahidrocannabinol (THC), which interacts with the cannabinoid receptor CB1R to produce its well known halucinogenic effects. However, the mechanism by which it produces its anaelgesic effects is less well known.
