If anyone has been watching the VA website they had a report about the medical use of Cannabis for Pain and PTSD. The document has not been available for the public but through the power of the Freedom of Information Act we were able to get a copy.
This 124 page, well researched document is probably one of the most extensive looks at Cannabis done by a Government agency. It not only looks at the use of Cannabis for Pain and PTSD but also looks at the harms of Cannabis use.
While they didn’t find much quality research on the medical use of Cannabis for Pain or PTSD they did find a lot of information. The research they cite from all kinds of sources indicate that the lack of research is limiting their ability to make quality decisions on Cannabis for Medicine or Safety.
Although cannabis is increasingly available for medical and recreational use, there is very little methodologically rigorous evidence examining its effects in patients with chronic pain or PTSD. There is limited evidence that cannabis may be helpful in improving pain and spasticity in selected populations with MS, but there is insufficient evidence in other populations. There is insufficient evidence examining the effects of cannabis in PTSD populations. Cannabis is associated with an increased risk of short-term adverse effects, but data on its effects on long- term physical health vary; harms in older patients or those with multiple comorbidities have not been studied. Cannabis has been associated with short-term cognitive impairment and potentially serious mental health adverse effects such as psychotic symptoms, though the absolute risk and application specifically to chronic pain and PTSD populations are uncertain.
