Short answer
A cannabis lozenge is an oral tablet that dissolves in the mouth. It carries THC, CBD, or both, and needs no smoke, battery, or lighter. Onset is 15 to 30 minutes under the tongue and 30 to 90 minutes when the dose is swallowed. A single piece holds 1 mg to 10 mg of THC. Start at 1 mg to 2.5 mg and wait two hours before a second piece.
What a lozenge holds
Dispensary lozenges use distillate, live resin, or isolate. Common pieces hold 2.5 mg, 5 mg, or 10 mg of delta-9 THC. CBD lozenges run 5 mg to 50 mg per piece. Some makers add CBN or CBG. Hemp-derived lozenges sold online fall under the 2018 Farm Bill, which caps delta-9 THC at 0.3 percent on a dry weight basis. That cap applies to the plant material, not to the milligram count in one piece.
Where to Buy THC Lozenges Online: A Practical Buying Guide
Onset and duration
Tissue under the tongue has a blood supply. THC crosses it and reaches plasma in 15 to 30 minutes. A swallowed dose passes through the stomach and liver first. That step converts THC to 11-hydroxy-THC, which binds some receptors with more strength. Onset then runs 30 to 90 minutes. Peak levels arrive at 1 to 2 hours. Effects last 4 to 8 hours. NIDA reports that oral THC has lower and more variable bioavailability than inhaled THC, so one milligram count can act on two people in two ways.
Dosing
Start at 1 mg to 2.5 mg of THC. Wait two hours before the next piece. Keep a log of dose, time, and effect for the first week. Oral doses stack. Three 5 mg pieces taken an hour apart act like one large dose at the two-hour mark.
Labels and lab tests
State-licensed packages list total THC per piece, total THC per package, batch number, and manufacture date. Hemp-derived packages vary by maker. Ask for a certificate of analysis from an ISO 17025 lab. The certificate should list cannabinoid potency plus screens for pesticides, heavy metals, and solvents. The FDA has not approved cannabis or delta-8 THC for any medical use. Approved cannabinoid medicines are dronabinol (Marinol, Syndros), nabilone (Cesamet), and cannabidiol (Epidiolex).
Why convenience matters
A lozenge needs no grinder, paper, battery, or flame. It fits in a pocket. The dose is fixed at the factory, so the user does not measure. That mix of portability and a set milligram count puts lozenges on dispensary shelves next to gummies and tinctures. The tradeoff is time. Inhaled THC reaches the brain in minutes. A lozenge takes 30 to 90 minutes. A user who wants a fast onset picks a vape. A user who wants a steady 4 to 8 hours picks a lozenge.
