Cannabichromene (cbc) and Oxycodone

Here is the interaction we found between these two, with the evidence behind it.

Moderate

CNS DEPRESSANTS

Why this applies to Oxycodone

Oxycodone falls under CNS DEPRESSANTS — the group Cannabichromene (cbc) interacts with.

Using cannabichromene with drugs that have sedative properties may cause additive therapeutic and adverse effects.
Animal research shows that cannabichromene, given as a single dose intraperitoneally, increases the sedative response to the drugs hexobarbital, barbital, and zoxazolamine. However, this effect was not maintained when cannabichromene was given continuously. After receiving cannabichromene daily for 7 days, the sedative effect of these drugs was reduced when compared with a control group or a single dose of cannabichromene.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist: oxycodone is a strong opioid that already slows down your brain and body, causing drowsiness, slowed breathing, and sometimes confusion or low blood pressure. CBC may add to that calming, sedating effect. In animal studies, a single dose of CBC made other sedative drugs work more strongly. So pairing it with oxycodone could, in theory, leave you more sleepy or foggy than expected.

I'll be honest with you though, this comes only from lab and animal research, not from people, so we really don't know how big a deal it is in real life. Still, with an opioid, I'd rather you play it safe. Please check with your pharmacist or doctor before combining the two, and never adjust your oxycodone on your own.

From our pharmacist’s overview on the Oxycodone page

“Oxycodone is a potent opioid painkiller, and anything that deepens its sedation can slow breathing itself, which is why this list deserves genuine respect. Of the 145 supplement and herbal ingredients on record, eight rate major, and the biggest cluster by far, 78 ingredients, adds extra drowsiness on top of the opioid's own.”

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.

About Oxycodone

What Is Oxycodone Used For?

Brand names: OxyContin, Roxicodone, OxyIR, Percolone, Oxecta, OxyNeo

Oxycodone is prescribed for pain severe enough to need daily, long-term opioid treatment — pain that hasn't responded well to non-opioid medicines or shorter-acting options. The extended-release form is designed for continuous pain control, not for occasional or as-needed use.

It is approved for adults and, in certain cases, for opioid-tolerant children 11 years and older who are already on opioid therapy. Because of the serious risks involved, it is reserved for situations where other approaches have genuinely fallen short.
