They may be safe, but there's one massive problem: There's practically no scientific data to support the idea that a CBD-infused topical cream is any more effective than other topical pain relievers, like 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 CBD 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.
In most cases (and in all cases in which the coffee shop doesn’t want to risk being sued), coffee shops can’t advertise CBD as doing much of anything, one way or another. While clinical trials attempt to determine an effective dose for a particular condition, says Esther, the growing “wellness empire” is free to leave the effects to your imagination. “People who are selling CBD don’t even have to make specific claims. The relationship between the actual amount of CBD and the effect doesn’t have to be very specific, because there is no specific effect that they’re talking about,” says Blessing. “So if I have a CBD latte, I might feel a little relaxed, or a little less neurotic, or who knows.”
CBD interacts with the body through the endogenous cannabinoid system (ECS) or endocannabinoid system. First discovered in the late 1980’s, the endocannabinoid system regulates the body’s homeostasis, or general state of balance, impacting such functions as mood, sleep, appetite, hormone regulation, and pain and immune response. Like an acrobat on a highwire, as the environment around us impacts our normal balance, the endocannabinoid system “corrects” by mediating our body’s reaction to keep us level.
"Cannabinoids have been found to have antioxidant properties, unrelated to NMDA receptor antagonism. This new found property makes cannabinoids useful in the treatment and prophylaxis of wide variety of oxidation associated diseases, such as ischemic, age-related, inflammatory and autoimmune diseases. The cannabinoids are found to have particular application as neuroprotectants, for example in limiting neurological damage following ischemic insults, such as stroke and trauma, or in the treatment of neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease and HIV dementia.
