For instance, there's something listed there called Purple Tangerines that was tested on June 22. Indica is its dominant strain and it has 13.2 percent THC, 0.2 percent CBD and 0.2 percent CBN.

Cannalytics' website organizes its results by category, such as concentrate, plant material, solid edibles, liquid edibles and topicals. Dates aren't listed on the first report page, but each listing has a PDF report with more information that gives the date. Pure Medicine Testing's web site was scheduled to go live the day this column is published, so I didn't get a chance to preview how it works. Although each lab will post results of all tests done, some clients might choose to not have their results listed for whatever reason. For instance, if they think the results show their medication to have a low potency, maybe they don't want that to be known.

These are the kinds of things we'll be seeing in the future as medical marijuana becomes more sophisticated and answers are developed for questions posed by patients and detractors. But like many other things in life, the proof is in the pudding. Analyze it and know what's in it, but there's probably no substitute for actually using it and figuring out what it does to you.
