CBD for Pain: Cost and Effectiveness
What Research Shows
A 2018 Cochrane review examined cannabis-based medicines for neuropathic pain. It included 16 studies with 1,750 people. The review found low-quality evidence. The medicines reduced pain by 30% or more in some people. The effect size was small. The review could not separate CBD from THC.
A 2020 review in the Journal of Pain Research looked at CBD for chronic pain. It found 11 studies. Most were small. The review said evidence is insufficient. The authors called for larger trials.
CBD does not bind to CB1 receptors with high affinity. It may affect pain through other pathways. These include serotonin receptors and TRPV1 receptors. Scientists do not understand how CBD works for pain.
CBD vs CBG for Pain: Which is Better?
Dosing and Forms
No standard dose exists for nerve pain. Clinical trials used doses from 2.5 mg/kg/day to 50 mg/kg/day. These doses were for seizures. For pain, doses varied. Some studies used 5 mg to 50 mg per day. Others used higher doses. More research is needed to find the right dose.
CBD comes in oils, capsules, and topical creams. Oils and capsules are taken by mouth. Topical creams are applied to the skin. The body absorbs CBD in ways that depend on the form.
Risks and Side Effects
CBD can cause tiredness, diarrhea, and changes in appetite. It can interact with blood thinners and epilepsy drugs. The FDA warns about liver injury. People with liver disease should talk to a doctor.
CBD can also interact with other medicines. These include drugs for depression, anxiety, and pain. Check with a doctor or pharmacist.
What to Do
Talk to a doctor before using CBD for nerve pain. Ask about drug interactions. Keep a pain diary. Do not stop prescription medicines without medical advice.
Ask your doctor about proven treatments for nerve pain. These include gabapentin, pregabalin, and certain antidepressants. These drugs have more evidence for nerve pain than CBD.
