Quick answer

There is no standard cannabis dose for nerve pain. Published trials use a wide spread: a few puffs of low-THC flower, or 2.5 mg to 20 mg of oral THC per day, or 100 mg to 600 mg of CBD per day in CBD-only studies. Your response depends on the cause of the nerve damage, your tolerance, and the product itself. Treat every number here as a range to discuss with a clinician, not a target to reach.

Before you start

Talk with the prescriber who manages your nerve pain. Ask about interactions with gabapentin, pregabalin, duloxetine, amitriptyline, opioids, and blood thinners. Confirm that cannabis is legal where you live and that your workplace or treatment program allows it. If you have a history of psychosis, severe heart disease, or cannabis use disorder, this route may not be right for you.

Why nerve pain resists a single dose

Neuropathic pain comes from damaged or misfiring nerves, not from tissue injury. That changes how the body responds to cannabinoids. Two people with the same diagnosis can need very different amounts, and the same person can respond differently on different days. Tolerance also builds with regular use, which pushes doses upward over time.

Ranges reported in clinical studies

These figures come from trials with small groups and short follow-up. Average results hide the people who got no relief and the people who stopped because of side effects. Your own titration matters more than any published average.

Step by step: finding your dose

  1. Get clearance from your clinician and write down your current medications.
  2. Choose one product with a stated THC and CBD percentage from a tested batch.
  3. Pick a single delivery method and stay with it. Mixing inhaled and edible doses makes tracking impossible.
  4. Take the smallest unit available. That means one puff, or 2.5 mg of oral THC.
  5. Wait the full onset window before redosing. Inhaled effects appear within minutes. Edibles can take two hours.
  6. Write down the time, amount, and pain score on a 0 to 10 scale.
  7. Hold that dose for two to three days before changing anything.
  8. Increase by the smallest step only if relief is absent and side effects are mild.
  9. Stop at the lowest dose that gives you useful relief.
  10. Take a two-day break every few weeks to check whether the dose still holds.

THC to CBD ratio

THC drives most of the pain relief and most of the impairment. CBD may soften THC side effects such as anxiety and rapid heart rate, though the evidence for CBD alone in nerve pain is thin. A 1:1 product is a common starting point because it limits how much THC you take per dose. High-THC products raise the risk of sedation, dizziness, and dependence.

Delivery method changes the math

Inhaled cannabis peaks in minutes and clears within a few hours, which makes it easy to titrate. Edibles convert THC in the liver and produce a stronger, longer effect that can last six hours or more. Tinctures under the tongue sit between the two. Topical products do not reach the bloodstream in meaningful amounts, so they rarely help nerve pain that runs along a limb.

Signs you went too high

Most of these fade within a few hours for inhaled products. Stay seated, drink water, and do not drive. Edible overdoses can last a full day.

When to stop and call a clinician

Stop and seek care if you have chest pain, fainting, a severe panic attack, or confusion. Call your prescriber if you need more cannabis each week to get the same relief, if you cannot skip a day, or if the pain is spreading.

Track what you take

Use a notebook or phone note with four columns: date, product and amount, pain score, and side effects. Bring it to your next appointment. A clear record is the only reliable way to know whether cannabis is helping you, and it gives your clinician something concrete to work with.
