  • Dizziness and vertigo are common side effects of cannabis use that can be caused by a drop in blood pressure or changes in brain activity related to THC.
  • THC can reduce cerebral blood flow and decrease blood pressure, leading to dizziness and lightheadedness, particularly in new users who have not yet built up a tolerance.
  • The endocannabinoid system (ECS) may play a role in modulating blood pressure and THC can mimic the effects of the endocannabinoid anandamide (AEA) in causing vasodilation (expansion of blood vessels) and lowering blood pressure.
  • To mitigate dizziness from cannabis, users can try new products or ingestion methods, consume weed companion foods, find their minimum effective dose, and track and optimize 15 different factors that can impact the cannabis experience.

Dizziness is a common but alarming side effect of cannabis. Dizziness can describe several different sensations like feeling faint, lightheaded, nauseous, unsteady, or woozy.

Dizziness is an impairment of spatial orientation. And vertigo is the feeling that you or objects around you are floating, spinning, or tilting. Rapid changes in head position can produce vertigo. That is why if you are lying down and quickly stand up you may experience dizziness or lightheadedness.

While dizziness can happen at any time, cannabis users often experience this side effect when they take a large hit of weed and experience an immediate drop in blood pressure.

What causes dizziness?

Several conditions can cause dizziness, from a drop in systolic blood pressure, to issues with your inner ear, to migraines, medication, vision issues, alcohol use, or even anxiety and stress. Treatment for dizziness or vertigo depends on the cause.

Many seasoned cannabis users have experienced vertigo or a feeling of dizziness when using cannabis.

Why does weed cause dizziness and lightheadedness? THC can reduce cerebral blood flow and decrease blood pressure, causing dizziness and lightheadedness.

How common is it to feel dizzy after using cannabis? A small study from 1992 indicates that dizziness from cannabis is common. The researchers note that marijuana is known to cause orthostatic hypotension, which is a sudden drop in blood pressure when you stand from sitting or lying down. Sixty percent of a small sample size experienced moderate to severe dizziness after smoking weed, but not after smoking a placebo joint. Subjects who reported severe dizziness had a drop in blood pressure as well as reduced cerebral blood flow.

Many people describe this feeling of dizziness after using cannabis as “greening out,” although greening out involves some other elements. To learn about greening out, check out our article What Is Greening Out?

Why does cannabis cause dizziness?

Cannabis produces its effects through chemical compounds that bind to receptors in your body and brain. Researchers indicate that the endocannabinoid system (ECS) may play a role in modulating blood pressure.

Anandamide (AEA), which THC mimics in the body, has been shown to produce vasodilatory effects. That means that AEA expands blood vessels and decreases blood pressure, just like THC.

Research indicates that cannabis users build up a tolerance to this side effect, so new users are more likely to experience dizziness than seasoned users.
