Dizziness is one of those symptoms that almost everyone recognizes, but few can easily describe. For some, it shows up as lightheadedness. For others, it feels like unsteadiness or a sense that the room is moving when it isn’t. It can be brief and passing, or persistent enough to reduce someone’s quality of life.
It’s not classified as a disease or single condition. It’s a signal that something in the system responsible for balance and orientation isn’t lining up.
Under normal conditions, the brain is constantly integrating input from the inner ear, the eyes, and the body. These systems work together to create a stable sense of where we are in space. When that integration falters—whether from a disturbance in the vestibular system, a mismatch in sensory input, or broader physiological stress—the result can be dizziness.
The causes are varied. Some originate in the balancing system itself, such as benign paroxysmal positional vertigo (BPPV) or vestibular migraine. Others come from outside that system, including cardiovascular changes, adverse effects from many medications, shifts in metabolism, or even anxiety-related processes. In many cases, it’s not one thing, but a combination that tips the system out of balance.
For patients, the impact can be substantial. Dizziness doesn’t just affect balance—it changes behavior. People begin to move differently, avoid certain environments, or limit activities that used to feel routine. Over time, this may lead to decreased confidence, physical deconditioning, and increased sensitivity to the symptom itself.
Treatment is often focused on handling symptoms. Medications such as antihistamines, antiemetics, or benzodiazepines are commonly used to reduce vertigo, nausea, or anxiety, respectively. While they can help in the short term, they also come with trade-offs—sedation, cognitive slowing, and, in some cases, interference with the body’s ability to recalibrate and adapt.

Concerns about Cannabis and Cancer-related Immunotherapies:
Some recent clinical observational studies have suggested that the co-administration of cannabinoid-based therapeutics and immunotherapy or immune checkpoint inhibitors in the treatment of certain types of cancer has been associated with worse overall survival rates (T. Taha et al., 2019; A. Biedny et al., 2020; G. Bar-Sela et al., 2020).
However, other studies have suggested that the co-commitment use of immune checkpoint inhibitors and cannabis-induced no such deleterious effects. More specifically, one trial was conducted on animals resulting in data suggesting that cannabis did not negatively affect the properties of immune checkpoint inhibitors (B. Waissengrin et al., 2023). The same authors compared the previous study results with findings from a cohort of 201 patients with metastatic non-small cell lung cancer who received treatment with monotherapy pembrolizumab as a first-line treatment and adjunct cannabis to treat mainly pain and loss of appetite. Their time to tumor progression was 6.1 versus 5.6 months, and overall survival differed between 54.9 versus 23.6 months in cannabis-naïve patients and cannabis-using patients, respectively. However, while numerically different, the authors write that these differences were not statistically significant, leading them to suggest that “These data provide reassurance regarding the absence of a deleterious effect of cannabis in this clinical setting.”
