Synopsis
Source of validity: Scientific
Rating (out of 5): 3
Cannabinoids, particularly cannabidiol (CBD) and tetrahydrocannabinol (THC), have been studied for their effects on the senses body system, especially regarding their influence on pain perception, intraocular pressure (vision), and neuroprotection. The most robust evidence exists for cannabinoids in the management of certain types of chronic pain, including neuropathic pain, which can affect sensory perception. There is also clinical evidence supporting the use of cannabinoids for reducing intraocular pressure in glaucoma, a condition that threatens vision. However, these effects are generally modest and cannabinoids are not considered first-line therapies. Additionally, cannabinoids can alter sensory perception (such as enhancement or distortion of taste, smell, and tactile sensations), but these effects are more often regarded as side effects rather than therapeutic uses.
Evidence for cannabinoids in treating other sensory disorders, such as hearing loss, tinnitus, or specific taste/smell dysfunctions, is minimal or lacking. In summary, while there is scientific validation—especially for pain management and possibly for glaucoma—the evidence is moderate (hence a rating of 3), and their use for broader sensory system support is not well established.
