The survey project is part of an HHC effort in alliance with the University of the City of London and the drug policy research group the Beckley Foundation, to compile a database based on the survey results that will let medical cannabis users look up which strains of cannabis are most commonly preferred to treat particular ailments.

HHC and its partners plan to key the questionnaire answers to the results of the extensive tests HHC has already done to categorize the various types of cannabis that come through their facility. The cannabis study project is still in its early data collection phase, but the hope is that the eventual result will be an easily accessible categorization of each strain of cannabis, and its customer preference status in treating each particular health problem.

...HHC’s survey takes into account not only the strain of cannabis each patient is using and evaluating, but also the particular batch of cannabis and the unique cannabinoid profile.

In theory, he says, over the course of two, three, four years of implementing questionnaire responses, the resulting database will allow the user to ask things like: “What did the largest number of multiple sclerosis patients prefer? Which strain did they prefer least? What’s the chemical difference—what’s the difference in cannabinoid profile between those two different strains of cannabis? So that we can start developing an actual, objective way of at least identifying cannabinoid profile with symptoms.”
