Cannabichromene (cbc) and Spinosad

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Spinosad and Cannabichromene (cbc) in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

How we checked

Why No Interaction Is Listed for Spinosad

Interactions in our licensed database are recorded against drug classes, not just single drug names. Spinosad is filed under a single classification — topical drugs. Cannabichromene (cbc) has documented interactions with 1 drug class — the most serious being cns depressants (moderate) — and none of Spinosad’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

What Spinosad’s Own FDA Label Lists

This is not an interaction — none of it involves Cannabichromene (cbc). These are the most notable effects listed in the ADVERSE REACTIONS section of Spinosad’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both.

  • Hair loss mentioned in 11.1% of FDA reports for Spinosad
  • Dry skin

From the ADVERSE REACTIONS section of the FDA label for Spinosad. Read the label on DailyMed › Where a percentage is shown, it is the share of 45 voluntary FDA FAERS reports for Spinosad that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Cannabichromene (cbc)’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Cannabichromene (cbc) side to compare — that is a limit of the record, not a statement that Cannabichromene (cbc) has no side effects.

Everything else you take

See Every Supplement That Interacts With Spinosad

The most serious there right now: Dimethylsulfoxide (dmso) (moderate), Turpentine Oil (moderate) and Alchemilla (minor).

By severity: 2 moderate · 1 minor.

From our pharmacist’s overview on the Spinosad page

“Spinosad (Natroba) is a lotion applied to the scalp to kill head lice, and because it works on the skin rather than inside the body, its interaction list is short. All three supplement ingredients on file, two moderate and one minor with nothing rated major, are things people also put on their skin.”

About Cannabichromene (cbc)

What is Cannabichromene (cbc)?

Cannabichromene (cbc)
  • Pain relief
  • Inflammation
  • Mood and anxiety
  • Skin and acne concerns
  • Brain and nerve health

Cannabichromene (CBC) is a non-intoxicating cannabinoid found in the cannabis plant that is being studied for possible pain, anti-inflammatory, and nervous-system effects. Almost all current evidence comes from laboratory and animal research, so we do not yet know how well it works or how safe it is in people. Talk with your pharmacist or doctor before using any CBC product, and avoid it during pregnancy and breastfeeding.

Cannabaceae · Flowers and resin of the cannabis plant (where the cannabinoid is concentrated) · Oils and tinctures, capsules, edibles, full-spectrum hemp extracts, vape products

An interaction check asks whether these two react with each other — it does not ask whether Cannabichromene (cbc) is a good idea for someone in your situation. Here is what our Cannabichromene (cbc) record says about it on its own.

Cannabichromene (cbc): dosing

There is no established or standardized dose for CBC. Because human research is so limited, experts cannot recommend a specific amount that is known to be safe or effective.If you choose to try a CBC product, follow the directions on the product label and consider starting low. Look for products that have been tested by an independent lab and provide a certificate of analysis.
