CODAS, Manuel et al. Cannabis in chronic pain - An indication supported by scientific evidence?. Rev. virtual Soc. Parag. Med. Int. [online]. 2018, vol.5, n.2, pp.12-18.  Epub Sep 01, 2018. ISSN 2312-3893.  https://doi.org/10.18004/rvspmi/2312-3893/2018.05(02)12-018.

Medicinal cannabis controversies are based on multiple factors. While the legality of its use is supported by some government laws, the disapproval on the part of the most important drug control agencies in the world remains constant. To date, it is set out if there is reliable and updated scientific evidence that disapproves of the use of cannabis for chronic pain. For this, search tools such as Pubmed, Google Scholar and Science Direct were used to review the literature on the Internet. The conclusions of more than thirty articles found on the web are similar in determining the great need for more scientific evidence to reaffirm the safety and reliability the use of cannabis for chronic pain including musculoskeletal pain, cancer-related pain, neuropathic pain and those of nonspecific type and origin. Side effects, drug interactions, packaging standardization and control and administration routes were also reviewed. Due to the scarcity of well-designed clinical studies with substantial samples and duration, essential factors for quality and reliability, it is concluded that there is currently no scientific evidence to approve or disapprove its use for medical purposes.
