30 minutes before you intend to fall asleep, place one quarter of a Tinc-Tac under the tongue and allow it to fully dissolve. Do Not Chew! One quarter is a single dose (5 mg of THC, 5 mg of CBD, 5 mg of CBG, 5 mg of CBN, 3 mg of melatonin). Individual need may vary, cut along the lines to create your custom dose.
