Cannabichromene (cbc) and Oxycodone, Naloxone

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

Moderate

CNS DEPRESSANTS

Why this applies to Oxycodone, Naloxone

Oxycodone, Naloxone 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

Targiniq ER pairs oxycodone, a strong opioid pain reliever, with naloxone to lower the risk of misuse. The oxycodone part already slows down your nervous system, which can leave you drowsy, foggy, or breathing more slowly. The concern here is simple overlap: CBC may add its own calming effect on top of that, so the two together could make you sleepier or more sedated than either alone.

I want to be honest about how weak this evidence is. It comes only from animal studies using older sedatives, not from people taking oxycodone. Interestingly, the sedation faded with repeated CBC dosing in those animals, so the picture isn't clear cut. Because opioids and breathing are nothing to gamble with, please check with your pharmacist or doctor before combining them, and never adjust your dose on your own.

From our pharmacist’s overview on the Oxycodone, Naloxone page

“Targiniq ER combines the opioid oxycodone with naloxone for around-the-clock pain, and because opioids can dangerously slow breathing once sedation stacks up, the 145 supplements on file here deserve genuine respect, above all the eight rated major. The largest group, 78 ingredients, layers drowsiness onto the opioid's own, with alcoho…”

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.
