In case you're interested, we did use methanol to extract. We have a validated extraction method (the exact extraction details are proprietary, sorry) as well as a validated analytical method. This means that we proved, much earlier than this study, that using our process we can extract all the...

This is a great idea. We're looking into it.

That's a very interesting idea. As of right now I don't think the vaporizer manufacturers want to name their products medical devices because that comes with tax increases. Also, this might have to wait until cannabis is reclassified from schedule 1 status. We've thought about expanding this...

The white paper captures the important details of the original scope, which was limited. The consumption of THC is linear throughout 30 draws, to r^2 = 0.97. If you extrapolate this line it will intercept the 'draws' axis at 40 draws. Subjective: When prompted they said they believed about...

There is much more to experiments than controlling all possible variables. As a matter of fact there are studies where precisely *not* controlling variables is key. Our aim was to test a genuine user experience and see what the numbers show. In the end, we thought data from user experience is...

If anyone has suggestions, questions, or comments about this study or future studies, we're listening!

Agreed, on all counts! We will try to set up more experiments, stay tuned...

Thanks for the welcome! We'll be here. Our thoughts are: enough theorizing, and lets get some data instead of making empty claims. We chose the MFLB because it is popular and wanted to help a large number of patients, and the MFLB is very popular. If this comes with inherent variability, so be...

Quibble away! We do have a part of that sample remaining for future confirmation, and we divided the same sample into roughly equal parts. I would not call these simply samples because they were measured to be roughly equal and were taken from a sample that was made to be more or less...

Thanks for the kind words! That's what we did, we ground up a couple grams, took a couple samples for a t=0 analysis, aliquoted the rest into 100 mg portions, and did just what you said. We sacrificed THC in the name of science... we think of it as a sacrifice to help everyone who vapes... like...

Exactly, you had the right idea of how it was done. Not after every hit, but after 5, 10, 15, etc. hits. Otherwise we'd still be at the lab :) What was very interesting indeed was the linearity of the results (r^2 = 0.97). If you stopped halfway, you consumed about half of the THC.

Not to put down Medical Jane, they did a fantastic job.

This was not our paper, but Medical Jane write-up of it. Here's a link to our original write-up: http://mcrlabs.com/wp-content/uploads/2014/07/White-Paper-Vape-Ex.pdf

It says in the paper that's how it was done: After each time point, remove all remaining cannabis for quantitative profiling by high-performance liquid chromatography (HPLC)
