THC Tincture Dosage Chart: mg Per Drop, Dropper & Bottle

THC Tincture Dosage Chart: mg Per Drop, Dropper & Bottle

Tincture bottles are labeled by total milligrams — 100mg, 300mg, 500mg, 1000mg — but nobody doses by the bottle. You dose by the drop or the dropper, and the label almost never tells you what those are worth. The math is simple once you see it laid out, and it's the difference between a pleasant 5mg evening and accidentally taking 30mg because "one dropper" sounded like one dose.

How to read your bottle

Two numbers matter: total THC in milligrams and bottle volume in milliliters. Most tincture bottles are 30ml (1 fl oz), and a standard dropper pulls about 1ml when squeezed once — so a 30ml bottle holds roughly 30 full droppers. Divide total mg by total ml and you have your working number: milligrams per dropper.

Drops are less precise. A milliliter is commonly around 20 drops, though drop size varies with the liquid and the dropper — treat per-drop figures as estimates and per-dropper figures as your reliable unit.

The chart: mg per drop and per dropper

All figures assume a standard 30ml (1 fl oz) bottle and ~20 drops per ml.

Read it the other way to find your dose. Want 5mg from a 300mg bottle? Half a dropper. From a 100mg bottle? A dropper and a half. From a 1000mg bottle? About 3 drops — which is why strong tinctures reward a careful hand and a marked dropper.

Matching the dose to your experience

The dose ranges are the same as any edible, because once swallowed, tincture is an edible. If you're new, our guide to choosing the right THC dose goes deeper.

Sublingual use changes the timing, not the dose: held under the tongue for 60-90 seconds, effects commonly arrive in 15-45 minutes instead of the 45-minute-to-2-hour edible window. Swallowed or added to food, tincture follows normal edible timing — give it the full 2 hours before judging, and if you overshoot, our guide on riding out a too-strong edible covers what actually helps.

Dosing a homemade tincture

Homemade bottles don't come with a label, but the same math works in reverse:

(grams of flower × THC% ÷ 100 × 1000 × decarb efficiency) ÷ finished volume in ml = mg per ml

Example: 3.5g of 20% THC flower, oven-decarbed at 90% efficiency, infused into 60ml of high-proof alcohol:

(3.5 × 0.20 × 1000 × 0.90) ÷ 60 = 10.5mg per ml — almost exactly the strength of a commercial 300mg bottle.

Run your own numbers through the dosage calculator, and if you haven't made a tincture yet, our cannabis tincture guide walks through the whole process, from decarb to strain to storage.

Homemade potency is an estimate, not a certainty — extraction is never 100% efficient, so your first doses from a new batch should start below the number the formula gives you.

Three habits that keep tincture dosing predictable

Dose by dropper, verify by count. Fill the dropper the same way every time (one full squeeze, held vertical) and count drops only when you need doses smaller than half a dropper.

Label the bottle with mg per ml, not total mg. "10.5mg/ml" on a strip of tape answers the only question you'll ever ask it. Date it too — tinctures keep for a year or more stored cool and dark, but you'll want to know which batch is which.

Change one variable at a time. New bottle, new dose, or new timing — not all three at once. Tolerance to tinctures tracks edible tolerance, so a dose that works from one bottle translates to any other bottle once you know both strengths.

FAQ

How many drops of tincture should I take?

It depends entirely on your bottle's strength. From a typical 300mg bottle (10mg per ml), a beginner dose of 2.5mg is about 5 drops; a standard 5mg dose is about 10 drops or half a dropper. From a 1000mg bottle the same 5mg dose is only 3 drops. Always work out the mg-per-drop figure for your specific bottle first.

How much THC is in one dropper?

A standard dropper holds about 1ml. Divide the bottle's total THC by its volume in ml: a 300mg tincture in a 30ml bottle is 10mg per full dropper, a 500mg bottle is about 17mg, and a 1000mg bottle is about 33mg. A full dropper of a strong tincture can be several times a standard dose.

How long does a tincture take to kick in?

Held under the tongue for 60-90 seconds, tinctures commonly take effect in 15-45 minutes — noticeably faster than eaten edibles. If you swallow the tincture straight away, or mix it into food or drink, it behaves like a regular edible: 45 minutes to 2 hours to onset, with longer-lasting effects.

Can I put tincture in food or drinks?

Yes — tincture is one of the easiest ways to dose food because the milligrams you add are the milligrams in the dish. Just remember that eaten tincture follows edible timing (45 minutes to 2 hours), not sublingual timing, and avoid adding it to anything still at a boil to protect potency.

How do I figure out the potency of homemade tincture?

Multiply grams of flower by THC percentage, by 1000, and by your decarb efficiency, then divide by the finished volume in ml. Example: 3.5g of 20% THC flower oven-decarbed (90%) into 60ml of alcohol is (3.5 × 0.20 × 1000 × 0.90) ÷ 60 ≈ 10.5mg per ml.
