Cannabis: The Evidence for Medical Use
Barnes MP, Barnes JC. Report published by Northumberland, Tyne & Wear NHS Foundation Trust, May 2016.
Literature review and discussion of strength of evidence of effectiveness for a wide variety of medical conditions.  This report was commissioned by the All Party Parliamentary Group for Drug Policy Reform (UK).  The authors note they received no renumeration other than a small grand from the APPG for Drug Policy Reform for their work and that they have no commercial interests in cannabis or cannabis products.  The report includes good discussions of the evidence – or lack thereof – for long-term negative effects often ascribed to marijuana use: psychotic disorders, dependence, respiratory system cancer, cognition, amotivational syndrome, and decreased brain volume.
