Dumb question - does the way the cannabis was consumed affect the accuracy of the device? Does it work as well for edible cannabis as it does for a joint?
The device works well for vaped and smoked cannabis. We generally see peak concentration 10 minutes after smoking, and a steady decay to 0 over the next few hours.
We are in the midst of testing for edibles. What we would expect is that the concentration is lower and that peak concentration should occur 1-2 hours post consumption, followed by decay. We will see how it goes!
