Turna et al:
Cannabis is commonly viewed as a natural alternative for a variety of medical and mental health conditions. Currently, anxiety ranks among the top five medical symptoms for which North Americans report using medical marijuana. However, upon careful review of the extant treatment literature, the anxiolytic effects of cannabis in clinical populations are surprisingly not well-documented.
Is it “surprising,” though? It seems routine for popular ideas about remedies to be so dominant that they obscure a glaring absence of evidence. Exactly the same goes for the pain-killing reputation of cannabis, unfortunately. (Only in that case its closer to evidence-of-absence than absence-of-evidence.)
