topical cbd requires thc

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.)

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.

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.

What Science Says About Hemp Creams for Pain Relief

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.

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.)

Biology lesson aside, all of this has yet to be proven in scientific studies on humans.

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.

THC and endocannabinoids are also similar in that they both bind to cannabinoid receptors called CB1 and CB2 receptors. These receptors, and the molecules that bind to them, are responsible for a wide range of biological functions, such as anti-inflammation and pain relief.

Researchers at the University of Colorado found that cannabis Topicals can effectively treat a variety of skin diseases including psoriasis, severe itching, and atopic and contact dermatitis.

What are the side effects of CBD or THC cream?

What does topically mean when it comes to cannabis creams? Your body’s natural endocannabinoid system (ECS) regulates your appetite, mood, and pain and pleasure receptors, among other functions. Cannabinoids THC and CBD, the active compounds in cannabis plants, are chemicals that activate that system. Your body also makes its own natural versions of these compounds, called endocannabinoids.

Topicals can treat breakthrough pain, neuropathic pain, and chronic pain. In fact, some studies have shown cannabis to be better for treating chronic pain than opioids . And since arthritis pain is frequently caused by joint inflammation, treating the inflammation itself relieves pain . This is why CBD oil or infused topicals are often seen to reduce pain for conditions such as rheumatoid arthritis or multiple sclerosis (MS).
