A cannabis microdose for pain relief is a small amount of THC, most often 1 to 2.5 mg per dose, taken to ease pain without the high. Start at 1 mg, wait two hours, then add 0.5 mg at a time until your pain drops. Most people find their working dose below 5 mg.

What counts as a microdose of cannabis?
A microdose is any amount below the level that makes you feel intoxicated. Cannabis users call that line the threshold dose, and it sits in a different spot for every person.
how to microdose cannabis for anxiety
- 0.5 to 1 mg THC: a starting point for people who are new to cannabis or sensitive to it.
- 1 to 2.5 mg THC: the range where most pain users report relief with a clear head.
- 2.5 to 5 mg THC: a mild body effect can show up here, along with drowsiness.
For scale, a standard recreational edible in states with legal cannabis holds 10 mg of THC. That is four to ten times higher than a microdose.

The method stays the same whether you use oil, capsules or flower: small dose, long wait, small increase.
- Set a baseline. Rate your pain from 0 to 10 at the same time each day for two days. Note sleep, mood and activity, so you have a number to compare against.
- Start at 1 mg THC. Measure with a dropper or a scored mint. Guessing from a chocolate bar breaks the whole system.
- Wait the full onset window. Two hours for edibles, oils and capsules. Fifteen to thirty minutes for inhaled flower or vapor.
- Re-rate your pain. Write down the new number and any side effects: dry mouth, sleepiness, racing thoughts.
- Add 0.5 mg on the next session if pain held. When a dose works, keep it steady for three days before you change anything.
- Stop at the sweet spot. The goal is the lowest dose that lowers your pain. Past that point, extra THC adds side effects, not relief.
Which cannabis product is easiest to microdose?
Tinctures and oils
A tincture gives you the finest control because you dose by drop. Look for a label that states mg of THC per ml, then do the math before you squeeze the dropper. A formula with a 1:1 THC to CBD ratio is a common first pick for pain.
Edibles and capsules
Factory doses are exact, but a 10 mg gummy is hard to cut into equal pieces. Buy 1 mg or 2.5 mg mints instead, and the measuring problem disappears.
Flower and vape
One small puff delivers an estimated 1 to 2 mg of THC, which makes inhalation the fastest option for breakthrough pain. Flower carries about 200 mg of THC per gram at 20% potency, so a single puff is a small slice of that.
Topicals
Balms and creams act on joints and muscles near the skin and produce no high. They are not a microdose in the classic sense, but many people use one alongside an oral dose.
Does CBD belong in the mix?
CBD does not cause a high, and some users find it stretches the effect of a small THC dose. A 1:1 ratio is the safest place to begin if you are new to cannabis. CBD can also change how your liver breaks down THC and other drugs, so keep the ratio the same from day to day.
How long does a microdose last?
- Inhaled: onset in 5 to 15 minutes, peak at 30 minutes, total effect 2 to 3 hours.
- Edible, oil or capsule: onset in 30 to 120 minutes, peak at 2 to 3 hours, total effect 4 to 8 hours.
Plan the dose around your day. Do not drive after any amount of THC, even a dose you cannot feel.
Track your doses like a prescription
Keep a simple log: date, time, product, mg of THC, mg of CBD, pain score before, pain score after, side effects. Patterns show up inside two weeks. That record is also what a doctor needs if you ask about your pain plan.
Mistakes that wreck a microdose plan
- Re-dosing too soon. Edibles need up to two hours. Taking a second dose at minute 30 leads to a dose that is too high.
- Splitting a 10 mg gummy by eye. The halves are never equal.
- Mixing with alcohol or sedatives. Both amplify the THC effect.
- Chasing a bigger dose after one good day. Tolerance builds when you raise the dose with no reason.
- Skipping the log. Without numbers, you cannot tell what worked.
When a microdose is not enough
If 5 mg brings no relief and no side effects, step up by 1 mg per session and keep logging. If you still get nothing at 10 mg, the problem may not be the dose. Talk to a clinician before you combine cannabis with opioids, benzodiazepines or blood thinners, and if you have heart, liver or kidney conditions.
Frequently asked questions
Can you microdose with flower?
Yes, but the measurement is coarser. Load a small pinch, take one short puff, and wait 15 minutes before the next one.
Will a microdose show up on a drug test?
Any THC intake can trigger a positive result. There is no dose small enough to guarantee a clean test.
Do you build tolerance to a microdose?
Some tolerance can appear with daily use. Two days off each week keeps the dose working at the same level for longer.
How long before you know your dose?
Most people need one to two weeks of steady sessions. Change one thing at a time and the answer arrives faster.
