Mode aims high for the perfect puff of weed – The Verge

For people who use cannabis for medicinal purposes, such as pain management, anxiety, and sleep, vaping the drug can be a bit of a trial-and-error process since you can’t be totally sure of the exact dose you’re getting like you can with a standard edible or pill. The makers of the Mode smart cannabis device say it solves the dosing problem, using a high-res pressure sensor to determine how much a user is inhaling and a prediction algorithm that determines how many micromilligrams a user is getting per puff based on the cartridge.

The company says it’s run hundreds of cannabis cartridges through its testing machines to identify each one’s unique characteristics, and the device has an accuracy rate of over 75 percent even without letting the app know which cartridge you’re using. (It’s in the high 80 percent range for known cartridges, the company claims.) Mode is compatible with thousands of standard 510 threaded cannabis cartridges, and it can be locked manually or remotely with the companion app. The company says the algorithm is still improving, and you’ll be able to download a new version to the device over Bluetooth.
