Should You Try Hemp Cream for Pain Relief?
Hemp pain relief creams or cannabis lotions claim to offer muscle relief for your tired body, but what do experts have to say?
Chances are if you're on this website and reading this story you currently have an achy muscle or seven somewhere on your body. You might be familiar with foam rolling, warm compresses, or even ice baths as a means of easing muscle soreness, but what about hemp cream for pain relief?
These topical ointments, creams, and lotions are infused with CBD, or cannabidiol, a compound found in the cannabis plant. Manufacturers claim it can help alleviate acute pain and muscle soreness. To reiterate for the uninitiated: CBD is not the same as THC because CBD does not have any psychoactive effects — aka it won't get you high.
Science has shown that cannabis is an effective pain reliever, reinforced in a massive new report from the National Academies of Sciences, Engineering, and Medicine. But there's a big difference between ingesting cannabis or its individual chemicals orally and absorbing it topically through your skin.

What Is Hemp Pain Relief Cream?
Hemp creams for pain relief are typically is made from infusing high-quality cannabis flowers in some kind of quality oil-coconut or olive typically-which extracts the active compounds, either CBD, THC, or both depending on the type of hemp used. (Here's a guide to the difference between THC, CBD, cannabis, and hemp.) This oil is then blended with other therapeutic herbs, such as arnica or lemongrass essential oils, that are thought to also ease pain.
If you read the ingredient list, often everything in the jar is straight from mother earth. As long as that's indeed the case with the cannabis cream you have your eye on, the formula is immensely safe, chemically, says Gregory Gerdeman, Ph.D., neurophysiologist who researches cannabinoid biology and pharmacology at Eckerd College in Saint Petersburg, FL. And since hemp pain relief creams are formulated to be topical (absorbing into the top layer of skin) and not transdermal (which would pass through the skin and into your bloodstream) there's no risk of getting high, explains Gerdeman. (P.S. Here's How Marijuana Affects Athletic Performance.)
"When it comes to cannabis-based topicals for muscle soreness or other pain relief, there's absolutely no reason why it should be a big deal to try," he says.
So cannabis lotions may be safe, but there's one problem: There's practically no scientific data to support the idea that a CBD-infused topical pain relief cream is any more effective than other topical pain relievers, such as Tiger Balm, BenGay, or Icy Hot. Michelle Sexton, a San Diego-based naturopathic doctor and medical research director of the Center for the Study of Cannabis and Social Policy says that her patients do seem to have a great interest in cannabis creams and ointments, and roughly 40 percent of them have indeed tried one. However, these people are in her office now because the topicals didn't work for them. "As a medical professional, my opinion is there's little evidence to back up the claims being made—it's all marketing for now," she says.
How CBD and Cannabis Might Help Pain Relief
There is an argument to be made for the simple fact that science hasn't caught up to the trend (and laws) of cannabis yet. (Here's what research has to say about the potential benefits of CBD and cannabis so far.) And there are doubtlessly researchers testing the efficacy of CBD creams for pain relief as we speak.
The theoretical logic is that are a few different ways CBD could help regulate pain — by increasing your natural endocannabinoids, decreasing your inflammatory response, and desensitizing your pain receptors (although it's still unclear whether this stands when absorbed topically compared to orally).
Let's start simple: Endocannabinoids are natural signals in your body that help maintain homeostasis by detecting and regulating hunger, pain, mood, and memory. (They're actually part of your post-workout exercise high.) CBD helps elevate your natural levels of pain-relieving endocannabinoids by blocking metabolism as they're moving around your body.
The second method of pain relief centers around the damage you do when you work out. When you strength train, you create micro-tears in your muscles, which is why you feel sore as you heal. Once your immune cells detect damage, they release inflammatory mediators in order to repair the tissue. CBD, though has the ability to limit the release of some proinflammatory signals, thereby helping with pain without thwarting the healing entirely, explains Gerdeman. (Related: Is Working Out When You're Sore a Bad Idea?)
Finally, you have receptors called TrpV1 that detect and regulate your body temperature. When activated, they put out heat, soothing your pain receptors. Using this channel, CBD makes these pain receptors hyperactive for a period of time, causing them to get hot, desensitizing them and downregulating those pain-sensing nerve endings.
What Science Says About Hemp Creams for Pain Relief
Biology lesson aside, all of this has yet to be proven in scientific studies on humans.
A study analysis in the Journal of Pain Research confirms that topical use of certain cannabinoid topicals can reduce pain in animals with inflammation or neuropathic pain. And science has found topical creams with THC and CBD help relieve pain for conditions like multiple sclerosis. But for the vast majority of chronic pain — and most certainly for acute pain like post-workout — the scientific jury is 100 percent still out. "There's a little bit of data in support of CBD for pain relief, but to go from animal to human is a giant leap," says Sexton.
"The pain and stiffness that comes post-workout or from overexertion certainly has a pro-inflammatory component to it, so it's reasonable to think CBD or other cannabinoids might have benefits, but we have no research to support this yet," adds Gerdeman.
The other issue? Topical hemp pain relief products and cannabis creams will treat anatomical structures within 1 centimeter of the skin—and the muscle where your actual soreness is located is going to be deeper than that, explains Ricardo Colberg, M.D., a physician at Andrews Sports Medicine and Orthopaedic Center in Birmingham, AL. (The good news: Since it doesn't need to be absorbed deeply, CBD and cannabis could do amazing things as a skincare ingredient.)
The fatty tissue can only hold so much oil, so, theoretically, if you apply enough of a cannabis cream to your skin, it might leak down into your skeletal muscle just out of diffusion, adds Sexton. But there's no study to show this, and that means you're going to be rubbing on a whole lot of the stuff.
This brings up an underlying issue with all CBD and hemp products: There is no regulation around how much active CBD or THC is in each cream or how much of the compound is needed to see relief. Read: "If you have three products that say 1 percent CBD infused in coconut oil, one could be great and the other two could be crap—that's the reality of cannabis medicine right now," says Gerdeman.

So, Should You Try Hemp Creams for Pain Relief?
Even still, cannabis creams could still reduce your acute pain or muscle soreness. That's because pretty much all of these hemp pain relief creams on the market right now have other scientifically-proven analgesic compounds, such as menthol, camphor, and capsaicin which are also found in other, non-CBD topical pain relievers. "Any cream with a heating or cooling sensation desensitizes the nerves to pain by distracting them with stimuli on top," explains Dr. Colberg. Plus you're often massaging the area as you apply, which improves circulation and reduces muscle spasms, he adds. (Get the best of both worlds by trying a CBD massage.)
So do you need CBD? All of the experts here agree that until there's more peer-reviewed research, all claims should be looked at as marketing hype and not evidence-based. (Or, they can be anecdotal. Read what happened when one woman tried CBD for anxiety.)
But there is an argument to be made for simply believing the CBD adds that special something. "Scientific literature says there's a 33 percent chance of the placebo effect helping people, so for some, just using a cream they believe can help will provide some relief," adds Dr. Colberg.
The short of it: Science hasn't confirmed CBD or hemp creams for pain relief will have any greater benefit than those without these compounds, but there's little-to-no risk in trying it out (other than wasting your money, of course). And if you believe in the power of CBD-infused creams, that may be enough to score some relief. (Consider trying these: Products That Personal Trainers Use to Relieve Muscle Soreness)
How to Find a Good Hemp Pain Relief Cream
If your state has legalized both compounds, look for a cream with 1:1 CBD to THC as well as another cannabinoid BCP (beta-caryophyllene) if possible, which manufacturers have seen better results with, Gerdeman suggests. Try Apothecanna's Extra Strength Relieving Creme ($20; apothecanna.com) or Whoopi & Maya's Medical Cannabis Rub (yes, that's Whoopi Goldberg's line), which was designed specifically for menstrual aches and pains (whoopiandmaya.com).
If you don't live in a legalized state, you can typically still get CBD creams. Since there's no regulation or standardized testing, your best bet is to find trustworthy brands that use creams free of toxins but with additional pain relievers like menthol, capsaicin, lemongrass, or camphor. Try Mary's Nutritionals Muscle Freeze ($70; marysnutritionals.com) or Elixinol's CBD Rescue Balm ($40; elixinol.com).
