What Are Cannabis Topicals and How Do They Work?
New methods of cannabis consumption are bringing us further away from the notion that cannabis belongs solely in a bong or joint – or that it has to get you high, for that matter. Cannabis-infused topicals are an example of how new modes of consumption are revolutionizing perceptions of cannabis as their accessibility, safety, and efficacy invite even the most unlikely patrons into the world of medical cannabis.
What are Topicals?
Topicals are cannabis-infused lotions, balms, and oils that are absorbed through the skin for localized relief of pain, soreness, and inflammation. Because they’re non-intoxicating, topicals are often chosen by patients who want the therapeutic benefits of cannabis without the cerebral euphoria associated with other delivery methods. Other transdermal innovations are fast arriving in the cannabis market, including long-lasting patches and tingly lubricants for patients and recreational consumers alike.
Strain-specific topicals attempt to harness certain terpenes and cannabinoids in a chemical profile similar to that of Blackberry Kush, Permafrost, Blueberry, or whatever other strains the processor wishes to imitate. Along with THC, CBD, THCA, and other cannabinoids, topical producers may also select ingredients and essential oils for additional relief, like cayenne, wintergreen, and clove.
How Do Cannabis-Infused Topicals Work?
Cannabis-infused lotions, salves, oils, sprays, and other transdermal methods of relief work by binding to a network of receptors called CB2. These CB2 receptors are found throughout the body and are activated either by the body’s naturally-occurring endocannabinoids or by cannabis compounds known as “phytocannabinoids” (e.g., THC, CBD).
Even if a topical contains active THC, it still won’t induce that intense “high” you’d get from smoking or ingesting cannabis. With most topicals, cannabinoids can’t breach the bloodstream; they only penetrate to the system of CB2 receptors. Transdermal patches, however, do deliver cannabinoids to the bloodstream and could have psychoactive effects with a high enough THC content.
What Symptoms Do Cannabis-Infused Topicals Treat?
Topicals are most popularly chosen for localized pain relief, muscle soreness, tension, and inflammation, but anecdotal evidence is beginning to show a widening spectrum of potential benefits, from psoriasis, dermatitis, and itching to headaches and cramping.
A THC-rich rub infused with cooling menthol and peppermint is a perfect way to wind down from a brutal workout or hike. For intense localized pain, you may try a warming balm that combines the deep painkilling properties of cannabinoids with a tingling, soothing sensation. Inflammation symptoms may require a different chemical profile, as Cannabis Basics' CEO Ah Warner explains:
“Arthritic pain is caused by inflammation. My products have [THCA] and CBD, both of which are anti-inflammatory. Active THC is not for inflammation, but when left in its acid form and combined with CBD, the two work to get rid of inflammation and the pain that comes with it.”
Different topicals have different benefits to offer depending on the way they are processed and the ingredients that are used, so experiment with various transdermal products to see what works for you. Canadians will see more and more options for topical remedies as regulations are enacted, and for sufferers of pain and inflammation, it’s worth exploring. You’d be surprised the difference that one special ingredient makes.
