How to Use Cannabis Tincture
A cannabis tincture is a liquid extract in a dropper bottle. The label lists THC in milligrams per milliliter (mg/mL) or total mg per bottle. To use one: shake the bottle, draw your dose into the dropper, squeeze the liquid under your tongue, hold it there for 60 to 90 seconds, then swallow. A first dose is 1 to 2.5 mg THC. Wait two hours before a second dose.
What You Need
- Bottle with a readable mg label
- Dropper or marked dosing syringe
- Timer
- Water
Steps
- Write down the mg per mL and the total mg per bottle.
- Shake the bottle for 10 seconds. Cannabinoids settle in a bottle that sits.
- Fill the dropper to your dose line, not to the top of the glass.
- Lift your tongue and squeeze the liquid under it.
- Hold the liquid for 60 to 90 seconds. Swallow the rest.
- Wait two hours. Write down the time and the dose.
Two Routes Into the Body
Under the tongue, veins move THC into the blood and past the liver. Onset runs 15 to 45 minutes. Swallowed, the liver converts THC into 11-hydroxy-THC, a compound with stronger effects. Onset runs 30 to 120 minutes. A tincture does both at once. Part of the dose absorbs under the tongue and the rest goes down the throat.
Dose
1 to 2.5 mg: first dose, no prior THC use. 2.5 to 5 mg: low dose for a user with some tolerance. 5 to 10 mg: common single dose in US retail products. Colorado sets 10 mg as one edible serving. 10 mg and above: heavy dose, with more risk of anxiety, fast heart rate, and nausea. The CDC notes that a swallowed dose can take up to two hours to peak.
Timing and Overlap
Sublingual effects last 2 to 4 hours. Swallowed effects last 4 to 8 hours. Two doses inside one hour can stack into a stronger effect than intended. Set a timer and keep it.
Storage
Keep the bottle in a dark cabinet away from heat. Alcohol-based tinctures hold potency for years. Oil-based tinctures (MCT, glycerin) hold for 1 to 2 years. Cap the bottle after each use. A 30 mL bottle holds about 600 drops at 0.05 mL per drop. Measure with the dropper, not with a kitchen spoon.
Convenience
Tinctures make no smoke and no odor. The dropper caps each dose in 0.1 mL steps, so one bottle covers weeks of use without a grinder, a lighter, or a battery. That dose control is the main reason tinctures show up in travel bags, hotel rooms, and workplace settings.
Limits
Alcohol tinctures can irritate the mouth. Glycerin versions taste sweet but hold less THC per mL. The FDA has approved specific prescription cannabinoid drugs, not retail tinctures. Federal law does not recognize cannabis tincture as a medicine. State rules on purchase, possession, and hemp-derived THC differ, and products above 0.3% delta-9 THC dry weight stay federally illegal outside licensed state programs.
