Can too much THC cause nausea?

Yes, too much THC can cause nausea.

THC, or tetrahydrocannabinol, is the main psychoactive compound in cannabis. It is responsible for the "high" feeling that people experience when they use cannabis. However, THC can also cause a number of side effects, including nausea.

Nausea is a common side effect of high-dose THC consumption, especially in new users. It is thought to be caused by THC's interaction with the brain's vomiting center. THC can also slow down the movement of food through the digestive system, which can contribute to nausea.

In addition to nausea, other side effects of high-dose THC consumption may include vomiting, dizziness, anxiety, paranoia, and sleepiness.

If you are experiencing nausea after using cannabis, it is recommended that you reduce your dose or stop using it altogether. You can also talk to your doctor about other ways to manage your nausea.
