Core buying advice
For neuropathy, the safest buying strategy is to choose products with clear lab-tested potency labels and to start with a CBD-dominant or balanced THC:CBD product at a low dose. Your first goal is not maximum relief but finding the smallest amount that reduces tingling, burning, or numbness without causing intoxication or side effects. Buy from a licensed dispensary that prints THC and CBD milligrams per serving or per gram, not vague percentages. Keep a log of dose, time, and symptom response. Work with a clinician who knows your other medications.

What to look for when buying
- Lab report with cannabinoid profile and contaminant testing for pesticides, mold, heavy metals, and residual solvents.
- Clear labels showing mg THC and mg CBD per unit, such as per gummy, capsule, mL of tincture, or gram of flower.
- Stated ratio, like 1:1 CBD:THC or 10:1 CBD:THC. Ratios help you compare products across brands.
- Product type. Tinctures, capsules, edibles, flower, vape cartridges, and topicals have different onset and duration.
- Low-dose options. Look for 1 mg or 2.5 mg THC units so you can titrate without cutting a gummy.
- No proprietary blends without numbers. If the label does not list THC and CBD amounts, skip it.
Dosage parameter bands
These ranges come from general clinical guidance and patient reports. Your response may differ. Start at the low end and adjust slowly.
Top Pick for Cannabis for Peripheral Neuropathy
- CBD-dominant: 10:1 to 20:1 CBD:THC. Start 5 to 10 mg CBD with 0.5 to 1 mg THC once daily.
- Balanced: 1:1 CBD:THC. Start 1 to 2.5 mg of each.
- THC-dominant: 5:1 or higher THC:CBD. Start 0.5 to 1 mg THC. This option carries more impairment risk.
- Titration step: increase by 0.5 to 1 mg THC or 5 mg CBD every 3 to 7 days.
- Common daily range after titration: 5 to 30 mg CBD and 1 to 10 mg THC. Some people need less, some need more.
- Inhalation onset: 5 to 15 minutes, duration 2 to 4 hours. Edible onset: 30 to 120 minutes, duration 4 to 8 hours. Tincture under the tongue onset: 15 to 45 minutes, duration 4 to 6 hours.
- Topicals: minimal systemic absorption. Useful for localized foot or hand pain, but not a substitute for internal dosing.
Titration schedule example
Week 1: 1 mg THC plus 10 mg CBD at bedtime. Week 2: if no relief and no bothersome side effects, increase to 2 mg THC plus 10 mg CBD. Week 3: 2 mg THC plus 20 mg CBD. Week 4: 3 mg THC plus 20 mg CBD. Stop increasing when symptoms ease or side effects appear. Hold at that dose.

Pitfalls to avoid
- Treating one gummy or one puff as one standard dose. Labels vary by product.
- Starting with high-THC products. Anxiety, racing heart, and paranoia are common at high doses.
- Mixing with alcohol, opioids, benzodiazepines, or muscle relaxants without medical advice.
- Driving or operating machinery after use. Cannabis can slow reaction time.
- Buying untested flower or vape cartridges from unlicensed sources.
- Increasing dose too fast. More THC does not equal more relief and can build tolerance.
- Ignoring sedation, dizziness, or confusion. Stop and reassess with your clinician.
- Assuming CBD has no interactions. CBD can affect liver enzymes and blood thinners.
- Stopping a prescribed medication on your own. Talk to your doctor first.
FAQ
What is a typical starting dose of medical cannabis for neuropathy?
A common start is 1 to 2.5 mg THC with an equal or greater amount of CBD, once daily in the evening. If you use CBD only, start 5 to 10 mg. Wait 3 to 7 days before increasing.
How long does it take to find the right dose?
Inhalation relief can appear in minutes. Edibles can take 1 to 2 hours. Full titration often takes 2 to 6 weeks. Keep a log of dose, time, and symptoms.
Is CBD or THC better for neuropathy?
Both are studied. CBD may help without intoxication. THC may help pain and sleep but can cause impairment. Many people use a combination.
Can I buy medical cannabis without a card?
In the US, medical cannabis requires a state-issued recommendation or card in medical-only states. Some states allow adult-use purchases. Check your local law.
What if I feel nothing after one dose?
Do not double the dose the same day. Wait at least 24 hours for edibles, then increase by the smallest measurable amount. Some people need several adjustments.
