For most adults, the top pick is a full-spectrum THC tincture dosed at 2.5 mg to 5 mg, held under the tongue 60 to 90 minutes before bed. That is a starting point, not a goal. The criteria behind it: THC-to-CBD ratio, speed of onset, your current tolerance, and whether your problem is falling asleep or staying asleep.

Tinctures behave differently from a joint or a vape. Oil- and alcohol-based drops absorb partly under the tongue and partly through the gut, so onset lands between 30 and 90 minutes and the effect lasts 4 to 8 hours. That long tail helps with night waking and hurts if you need to be sharp at 6 a.m.

Low-dose THC tincture (2.5 mg to 5 mg)

The standard entry point. One drop from a 1,000 mg per 30 mL bottle is roughly 1.7 mg, so a graduated dropper matters more than the label claim.

Pros

Can You Add Cannabis Tincture to Coffee? Yes, Here's How

Cons

Use it if you are new to tinctures, you dislike feeling high, or you wake once or twice and want a gentle push back to sleep.

Balanced 1:1 THC to CBD tincture (5 mg each)

CBD does not sedate on its own, but it can soften the edge of THC and stretch the effect for some people.

Pros

Cons

Use it if plain THC makes you tense, or if your sleep problem runs alongside daytime anxiety.

THC with CBN tincture

CBN is a minor cannabinoid sold as THC's sedation partner. Human sleep data is thin and most support is anecdotal. Blends that people report working usually carry 5 mg to 10 mg of THC, not CBN by itself.

Pros

Cons

Use it if you fall asleep fine but wake in the second half of the night and low-dose THC alone fades too early.

CBD-dominant, THC-free tincture

A reasonable first step if you want zero intoxication or you face drug testing.

Pros

Cons

Use it if you are THC-averse, or you want to test whether cannabinoids help you at all before adding THC.

High-dose THC tincture (10 mg and up)

Pros

Cons

Use it if you are an experienced user who has already titrated up in steps and still gets no effect below 10 mg. Not a starting dose.

How to titrate: a seven-night plan

  1. Nights 1 to 3: 2.5 mg, taken 75 minutes before bed. Log sleep onset, wake-ups, and how you feel at breakfast.
  2. Nights 4 to 5: no change? Move to 5 mg.
  3. Nights 6 to 7: if 5 mg works, hold there. If not, add 2.5 mg, not 5.
  4. Treat 10 mg as a ceiling unless a clinician tells you otherwise.

Hold a working dose for a full week before touching it. Tolerance builds with nightly use, so plan two or three THC-free nights each week to keep the dose effective.

Timing and delivery details

Hold the oil under your tongue for 60 to 120 seconds before you swallow. Eat lightly beforehand, since a heavy meal delays absorption further. Alcohol and prescription sedatives stack with THC and raise the risk of falls and slowed breathing.

Safety and legal notes

Cannabis is not FDA-approved for insomnia and it can interact with blood thinners, benzodiazepines, and some antidepressants. Sleep apnea, restless legs, and depression need their own treatment. Talk to a clinician first if you are pregnant, under 25, or taking prescription sedatives.
