Medicinal Cannabis

Although widely touted as a cure-all in the media and by our politicians, the scientific evidence suggests that medicinal cannabis helps between 1 in 12 to 1 in 24 patients as regards pain reduction, and harms via serious side effects between 1 in 6 to 1 in 12 patients [1]. Therefore, it harms more patients than it helps in its current formats and is rarely indicated for prescription.

Research needs to be done to increase the help and reduce the harm related to novel formulations.

PEA (palmitoylethanolamide) is a natural fatty acid that stimulates the body's own cannabinoid production and may be the safest way to currently access the cannabinoid receptor [2-4]. PEA is an over the counter medication.
