Can Too Much Weed Cause Vertigo?

Vertigo is a sensation of spinning or feeling off-balance, where an individual perceives themselves or their surroundings to be moving. It is a symptom rather than a condition, often accompanied by dizziness. This article explores the potential relationship between cannabis consumption and experiences of vertigo, addressing how cannabis might induce these sensations for some individuals.

Cannabis and Vertigo: The Connection

For certain individuals, cannabis use can lead to sensations of dizziness or vertigo. This is a commonly reported side effect, with intensity varying significantly among individuals.
Factors such as dosage and potency, particularly tetrahydrocannabinol (THC) concentration, influence the likelihood and severity of these effects. Higher THC content is often associated with a greater potential for inducing dizziness. Individual sensitivity also plays a role, meaning some people may be more susceptible to these effects, even at lower doses.

How Cannabis May Induce Vertigo

Cannabis can contribute to vertigo through several physiological mechanisms. One primary way is orthostatic hypotension, a sudden drop in blood pressure upon standing. THC, the main psychoactive compound, acts as a vasodilator, widening blood vessels and leading to a temporary decrease in blood pressure and lightheadedness.
This blood pressure reduction can also lead to altered cerebral blood flow, meaning less blood reaches the brain. Such changes in brain circulation can contribute to dizziness and disorientation. Cannabis may temporarily affect how blood circulates in specific brain regions, influencing balance.
The endocannabinoid system (ECS) plays a role in maintaining balance. Cannabinoid receptors are present in the central vestibular system, which coordinates balance and spatial orientation. THC’s interaction with these receptors can directly influence the vestibular system, although the exact mechanisms are still being researched.
Cannabis also impacts various neurotransmitters, the brain’s chemical messengers. THC influences neurotransmitters like gamma-aminobutyric acid (GABA) and glutamate, which regulate brain activity, balance, and perception. By interacting with these systems, cannabis can temporarily disrupt the brain’s natural self-regulating processes.

Managing Vertigo After Cannabis Use

If you experience vertigo after consuming cannabis, several immediate steps can help manage the symptoms. Find a safe, comfortable place to sit or lie down. Resting in a quiet, dark environment can help alleviate the spinning sensation and prevent falls.
Staying well-hydrated is important, as dehydration can worsen dizziness. Drinking water can help stabilize blood pressure and reduce symptom intensity. Avoid consuming more cannabis if you are experiencing vertigo, as additional intake could exacerbate effects.
A light snack can help stabilize blood sugar levels, which may also mitigate dizziness. When using cannabis, especially edibles, start with a very low dose and gradually increase it to prevent overwhelming side effects. Choosing strains with a higher cannabidiol (CBD) to THC ratio might also reduce dizziness.

When to Seek Professional Medical Advice

While cannabis-induced vertigo is often temporary, professional medical advice is important in specific situations. If the vertigo does not subside, becomes severe, or is persistent, medical consultation is recommended.
Immediate medical attention is necessary if vertigo is accompanied by other severe symptoms. These include a sudden, severe headache, chest pain, difficulty breathing, numbness or weakness in the arms or legs, double vision, slurred speech, confusion, fainting, or seizures. These symptoms could indicate a more serious underlying medical condition, such as a stroke, that requires urgent evaluation.
Individuals with frequent vertigo after cannabis use should consult a healthcare provider to investigate underlying sensitivities or conditions. Those with pre-existing health concerns, particularly heart conditions, blood pressure issues, or neurological disorders, should discuss cannabis use with their doctor. Cannabis can pose greater risks for these groups and professional guidance is beneficial.
