Can I buy CBD oil with FSA?

Editorial team Published on

Generally, standard over-the-counter CBD oil and other hemp-derived cannabinoid products are ineligible for purchase or reimbursement using FSA (Flexible Spending Account) or HSA funds. This is because the IRS has not classified general CBD as a qualified medical expense without formal guidance, though FDA-approved prescription medications containing CBD (like Epidiolex) are treated differently.

Do you need a prescription to get CBD cream?

You do not need a prescription to buy most CBD creams, as they are widely sold over the counter.

Purchasing Rules

  • Hemp-derived creams: Creams made from industrial hemp containing less than 0.3% THC do not require a prescription or medical card.
  • Marijuana-derived creams: If a topical cream contains higher levels of THC, it may require a medical marijuana card or prescription depending on local state laws.
  • Prescription exception: The only FDA-approved prescription CBD product is Epidiolex, an oral medication used for specific seizure disorders, not for skin creams.

Product Safety

  • Regulation: The FDA does not regulate over-the-counter CBD topicals for safety or effectiveness.
  • Quality checks: Look for third-party lab test results, often called a Certificate of Analysis, to verify the potency and purity of the cream.

What is the downside of CBD oil?

The main downside of CBD oil includes common side effects like drowsiness, dry mouth, diarrhea, and reduced appetite, alongside risks of liver injury and dangerous drug interactions.

Common Side Effects

  • Digestive issues: Diarrhea, nausea, and changes in appetite.
  • Fatigue: Drowsiness, sedation, and general lethargy.
  • Mouth changes: Dry mouth.

Major Health Risks

  • Liver toxicity: High doses can cause elevated liver enzymes and potential liver damage.
  • Medication interactions: CBD interferes with liver enzymes (like cytochrome P450), which can dangerously change how your body processes blood thinners, antidepressants, and other drugs.
  • Product unreliability: Over-the-counter products are largely unregulated by the Food and Drug Administration (FDA), meaning labels may inaccurately state CBD amounts, or contain hidden THC and contaminants like heavy metals.

What is the strongest CBD over the counter?

Over-the-counter (OTC) CBD products reach strengths of up to 7,500 mg to 10,000 mg of total CBD per bottle, translating to high-potency doses of 200 mg to 250 mg per serving.

Highest-Potency Over-the-Counter CBD Brands

  • cbdMD: Offers high-strength tinctures reaching up to 7,500 mg per bottle, delivering around 250 mg of broad-spectrum CBD per serving.
  • Lazarus Naturals: Noted by health reviewers at Healthline for high-potency options, featuring full-spectrum CBD tinctures up to 6,000 mg and high-dose softgels.
  • NuLeaf Naturals: Provides full-spectrum organic hemp oils in large bottle sizes scaling up to 6,000 mg.
  • CBDistillery: Features concentrated full-spectrum and THC-free options reaching up to 5,000 mg per bottle.

What "Strong" Means for CBD

  • High Potency: Generally defined as containing 50 mg or more of CBD per single serving.
  • Formulation Types:
    • Full-spectrum contains trace amounts of THC (up to 0.3%) alongside other cannabinoids to create an "entourage effect".
    • Broad-spectrum offers multiple cannabinoids and terpenes without THC.
    • Isolate is pure CBD with all other plant compounds removed.
  • Safety Note: Over-the-counter CBD is not strictly regulated by the FDA for purity or potency, and high doses can interact with medications like sedatives or blood thinners. Always check third-party Certificates of Analysis (COAs).

What should you not mix CBD with?

You should not mix CBD with certain prescription medications, alcohol, or sedatives that carry a grapefruit warning or affect liver enzymes.

Medications with a Grapefruit Warning

  • Blood thinners: Such as warfarin, which can build up to dangerous levels in your blood.
  • Thyroid medications: Like levothyroxine.
  • Seizure medications: Including clobazam, lamotrigine, and valproate.
  • Heart rhythm drugs: Such as amiodarone.

Sedatives and Central Nervous System Depressants

  • Alcohol: Combining alcohol and CBD increases drowsiness, fatigue, and impaired coordination.
  • Benzodiazepines: These sedative medications can cause excessive sleepiness and slowed reactions when interacting with CBD due to competing metabolic pathways.
  • Opioids: Prescription pain-relieving medications mixed with CBD may lead to heavy sedation and slowed breathing.
  • Antidepressants: Certain classes of antidepressants utilize the same liver pathways, which can alter the concentration of the medication in the bloodstream.

Is CBD harder on the liver than alcohol?

No, CBD is not harder on the liver than alcohol; alcohol is vastly more toxic and a leading cause of chronic liver disease, whereas CBD is generally safe for the liver at normal doses.

Alcohol and Liver Damage

  • High toxicity: Alcohol directly causes oxidative stress, inflammation, and cell death in the liver.
  • Severe conditions: Chronic heavy drinking leads to fatty liver, alcoholic hepatitis, and irreversible cirrhosis.

CBD and Liver Safety

  • General safety: Standard, everyday doses of CBD (under 100 mg to 200 mg daily) are not known to harm healthy livers.
  • Potential benefits: Preclinical and observational research suggests CBD may actually reduce liver inflammation, fat buildup, and oxidative stress.
  • High-dose risks: Extremely high therapeutic doses—often exceeding 1,500 mg per day or doses used for severe epilepsy—can cause temporary elevations in liver enzymes, signaling potential stress.
  • Medication interactions: CBD is processed by liver enzymes, so taking high amounts alongside certain prescription drugs or heavy alcohol can increase liver strain.

Why don't doctors recommend CBD?

Doctors rarely recommend over-the-counter CBD because of a lack of strict regulation, insufficient clinical proof for most health claims, and potential safety risks.

Lack of Regulation and Purity

  • Unregulated market: Over-the-counter CBD is sold as a dietary supplement, meaning the FDA does not strictly test or regulate its safety, purity, or manufacturing standards.
  • Mislabeling: Independent studies show that many commercial products contain vastly different amounts of CBD than what is listed on the label, and some even contain hidden THC or contaminants like heavy metals and pesticides.

Insufficient Scientific Evidence

  • Limited proof: Aside from an FDA-approved prescription medication called Epidiolex used for rare seizure disorders, there is a lack of high-quality human clinical trials proving that CBD effectively treats conditions like chronic pain, anxiety, or insomnia.
  • Marketing vs. science: Aggressive commercial advertising often promotes CBD as a cure-all, but scientific research has not caught up to validate these claims.

Safety and Side Effects

  • Drug interactions: CBD can interact negatively with many common prescription drugs, including blood thinners, heart medications, and psychiatric treatments, potentially causing dangerous side effects.
  • Adverse effects: High doses of CBD have been linked to liver enzyme abnormalities and liver toxicity, alongside milder side effects like fatigue, diarrhea, and nausea.

Which form of CBD is best for pain?

Topical CBD creams and balms are best for targeted, localized pain like sore joints or tight muscles, while oral oils and gummies work better for widespread aches.

Localized Pain (Topicals)

  • Best for: Arthritis in specific joints, sore shoulders, or tight back muscles.
  • How it works: You rub creams, balms, or salves directly onto the skin over the painful area.
  • Onset: Starts working within 30 minutes in that exact spot without entering your bloodstream.

Widespread Pain (Oils and Tinctures)

  • Best for: General body aches or pain linked with anxiety and poor sleep.
  • How it works: You place drops under your tongue and hold them for a minute before swallowing.
  • Onset: Absorbs quickly into the system, usually within 15 to 45 minutes.

Consistent Dosing (Gummies and Capsules)

  • Best for: Daily maintenance and people who want an easy, measured dose.
  • How it works: You swallow them like a regular vitamin.
  • Onset: Takes 1 to 2 hours because your digestive system must process them first.

Choosing the Extract Type

  • Full-spectrum: Contains all hemp plant compounds and trace THC (under 0.3%), which may boost relief through the "entourage effect".
  • Broad-spectrum: Contains multiple hemp compounds and cannabinoids, but has no detectable THC.
  • Isolate: Pure CBD with no other plant compounds or THC.

Is CBD hard on the liver or kidneys?

CBD (cannabidiol) can affect the liver by raising liver enzymes at high or even consumer-level doses, but it does not show a clear harmful effect on healthy kidneys.

Effects on the Liver

  • Elevated Enzymes: Research shows that CBD can increase liver enzymes (such as ALT), which act as a warning sign of potential liver cell stress or damage.
  • Dosage and Risk: While high doses (often used in prescription forms like Epidiolex) carry a known risk of liver toxicity, recent studies note that some people experience enzyme elevations even at lower, over-the-counter consumer doses.
  • Drug Interactions: The liver breaks down CBD using the cytochrome P450 enzyme system. Taking CBD alongside other medications processed by these same enzymes (like certain blood thinners, seizure medications, or over-the-counter pain relievers) raises the risk of liver strain.
  • Reversibility: In most cases where liver enzymes rise due to CBD, levels return to normal within a couple of weeks after stopping use.

Effects on the Kidneys

  • Minimal Direct Impact: Current evidence does not show that CBD causes direct toxicity or harm to healthy kidneys.
  • Excretion: The kidneys help filter and eliminate the processed waste products (metabolites) of CBD from the body, but standard use does not appear to impair renal function.
  • Pre-existing Disease: People who already have chronic kidney disease should exercise caution and speak with a doctor, as compromised organ systems process substances differently.
