CBD and THC may be safe for use with opioid pain relievers, animal study suggests

Linda Rider

Conclusions from a new animal examine counsel that cannabidiol (CBD) and tetrahydrocannabinol (THC) may possibly be harmless for use with opioid discomfort relievers. Despite the fact that much more experiments are necessary, the outcomes propose that these compounds may possibly be a small-possibility way to cut down the dose of opioids needed to relieve ache.


There is intense fascination in making use of health-related marijuana in clients with chronic suffering because compounds in marijuana like CBD and THC may perhaps create discomfort aid by themselves or enrich the suffering-relieving outcomes of opioids. This implies men and women could most likely use reduce doses of opioids and continue to get aid from agony. Getting much less soreness medication could also lead to a decreased hazard of addiction or physical dependence to opioids.”

The researchers uncovered that CBD and THC do not boost the worthwhile consequences of opioids. This signifies that these compounds may not maximize the threat for addiction when utilised in conjunction with opioids.

Carey will present the new analysis at the American Society for Pharmacology and Experimental Therapeutics annual conference in the course of the Experimental Biology (EB) 2022 assembly, to be held April 2–5 in Philadelphia.

In the new study, the scientists gave rhesus monkeys the prospect to opt for a meals reward or an injection of the opioid fentanyl. They then examined regardless of whether CBD, THC or mixtures that contains equally compounds afflicted the variety of situations monkeys picked fentanyl over foodstuff. They uncovered that a huge range of doses of CBD or THC both of those on your own or in a mixture did not improve or lessen the quantity of times they picked fentanyl.

“Offering the animals the opportunity to pick out concerning a drug injection and a foodstuff reward served us to relatively replicate options a human drug consumer may encounter, these as whether or not to expend funds on medications or meals,” stated Carey. “Getting the possibility of responding for food is also practical for learning prescription drugs like THC that generate sedative outcomes. It will help exhibit the animal is reallocating conduct from drug to foods selection rather of merely shutting down reaction for a drug because of to sedation.”

The researchers are now conducting other studies to evaluate whether CBD and THC can minimize indicators of opioid withdrawal and relapse.

“A massive reason why folks keep on to just take opioids right after they grow to be addicted is the look of withdrawal symptoms,” claimed Carey. “We are employing what we uncovered from this examine to ascertain regardless of whether these doses – which didn’t alter alternative for food items or drug benefits – may well aid relieve opioid withdrawal or lower relapse and drug in search of conduct next periods of abstinence.”

The scientists caution that opioid use problem is a complicated disorder and there are numerous aspects to look at when developing a drug to handle it. Despite the fact that this examine suggests that THC and CBD do not improve the satisfying effects of opioids, they say that prior to making use of these results to individuals, it will be essential to decide no matter whether these remedies change other pathological procedures concerned with opioid use and to better comprehend any dangers that may possibly be related with their use.

Lawrence Carey will present this investigate from 10 a.m.–12 p.m., Monday, April 4, in Exhibit/Poster Hall A-B, Pennsylvania Convention Centre (Poster Board Amount B12) (summary) and 1:431:56 p.m., April 4 in Space 113 A (summary).
