Cannabis tinctures & sublingual oils
Oil under the tongue, 60 seconds, swallow. This route bypasses the liver and delivers 4× the active per dose vs swallowing.
Sublingual = uptake through oral mucosa. Onset 15–30 min, duration 4–6 h, bioavailability ~20 %. Math: % × 10 = mg/ml. A 10 % oil = 100 mg/ml = ~3 mg/drop. CBD starter dose: 10–20 mg/day. MCT is the best carrier.
How sublingual absorption works
The oral mucosa is thin and richly vascularized. Fat-soluble cannabinoids diffuse straight into the bloodstream.
Onset 15–30 min, higher share reaches circulation. Hold ≥ 60 seconds.
Dose math
% × 10 = mg/ml. 5 % = 50 mg/ml, 10 % = 100 mg/ml, 20 % = 200 mg/ml.
Standard pipette: ~0.05 ml/drop.
