Does this test for edibles? If a user has THC in their blood stream but not from their lungs, will this show up? Alcohol is absorbed through the stomach, passed through the bloodstream and released through the lungs. Since THC is fat soluble, I can't imagine it interacts the same way to allow for breathalyzer testing of people who have taken edibles.

Per OP:

> We are actually testing edibles right now! Early results don't look so good, but that could be because we were using our crappy LC-MS for detection instead of our sensor. We'll keep everyone updated with how it goes!

I don’t understand how this gadget works, but if it’s detecting residual THC in the lungs from smoke or vapor, I can’t see how this improves over blood testing as a proxy for impairment; I can see how LEO would nonetheless like to have it as it further empowers roadside judgements.

I'm curious to see how you will test for this because the liver changes the chemical composition of THC and the body processes it differently than if you smoked. The THC that was eaten will show up chemically different than of it was smoked too. This looks very promising so far!
