MCR Labs out of Framingham, MA had done research back on December 2nd 2014, releasing the results of reclaim recovered from dab rigs and tested the oil in different consistency's.
I personally have always wondered about the amount of medical THC and Cannabinoids would be in used oil and after further research, they by far had the best results visually to see the exact output.
I recommend that connoisseurs of dabbing use reclaim in making edibles for a longer lasting (not to mention better tasting) product.
3rd Test: The picture for the results was corrupted but the results are as follows:
The Max THC was 50.3%, the Max CBD was 3.7%, and the CBN was 7.5%
Test 1 and 3 where removed by means of collecting from drop down.
Test 2 Was removed from by means of scraping direct inject on dab nail.
Test 4 was removed by torch to thin the viscosity for removal and sat for 6 months.
The more you know, The more you grow, The more you stay pro.
