Short answer

For pain relief with oral cannabis, start at 2.5 mg THC per dose if you have never used THC, or 5 mg if you have some tolerance. Wait at least 2 full hours before you judge the result. Increase by 2.5 mg per dose only after 24 hours at the same level. Capsules and edibles both pass through the liver, so they produce a slower, longer, and stronger effect than inhaled cannabis. That delay is the main reason people accidentally overshoot.

Cannabis for Pain Relief Reviews 2025: The Ultimate Comparison

Why oral cannabis behaves differently

Swallowed THC is converted in the liver into 11-hydroxy-THC, a metabolite with a longer duration and a heavier body effect. Inhaled THC peaks in minutes. Oral THC peaks between 1 and 4 hours after you swallow it, and the effect can last 6 to 8 hours or longer.

medical cannabis for pain relief vs opioid

  • Capsules: a fixed, measured dose per unit. Absorption still varies with what is in your stomach.
  • Edibles: the food matrix, fat content, and portion size change how much THC reaches your bloodstream.

Starting dose ranges by experience

  • No prior THC use: 2.5 mg THC
  • Occasional use: 2.5 to 5 mg THC
  • Regular oral user: 5 to 10 mg THC
  • High tolerance: 10 mg or more, only with clinician guidance

These are starting points, not targets. Older adults and people taking sedatives, opioids, or blood thinners should begin at the low end.

How to titrate your dose

  1. Choose one product and note the exact THC and CBD milligrams per capsule or serving.
  2. Take 2.5 mg THC with food at the same time of day.
  3. Wait 2 hours before you rate your pain. Do not redose inside that window.
  4. Write down the dose, the time, the pain score, and any side effects.
  5. Repeat the same dose for 2 to 3 days to see whether relief holds.
  6. Increase by 2.5 mg only if relief is poor and side effects are mild or absent.
  7. Stay at the lowest dose that lowers your pain. Stop increasing when side effects appear.

Ratio choices for pain

Many clinicians suggest starting with a CBD-dominant product, such as 1 mg THC to 10 mg CBD, or an even 1:1 ratio. CBD may blunt some THC side effects, and it does not add intoxication at typical doses. Higher THC ratios suit people who already tolerate THC well.

Cannabis for Back Pain Relief: Is Convenience the Key?

If you take too much

  • Sit or lie down in a calm room and set a timer for 2 hours.
  • Drink water and eat a light snack.
  • Skip the next scheduled dose until you feel normal.
  • Call poison control or seek care for chest pain, severe confusion, or vomiting that will not stop.

Convenience and consistency

Capsules win on portability and repeatable dosing. A blister pack or bottle travels well, carries a printed milligram count, and removes the guesswork of cutting a gummy. Edibles win on cost per milligram and taste. Whichever you pick, buy from one producer and one batch when you titrate, because label accuracy varies between brands. Convenience matters only if the product keeps your dose steady.

When to talk to a clinician

Cannabis is not a first-line treatment for chronic pain, and evidence for oral THC in neuropathic and cancer pain is mixed. Talk to a clinician before you combine cannabis with opioids, benzodiazepines, or antidepressants, and before you use it during pregnancy, while breastfeeding, or under age 21.
