There is a rare disorder called cannabinoid hyperemesis syndrome (CHS) that is marked by severe bouts of nausea and vomiting. This disorder arises in some people who have been taking very large amounts of cannabis over a long period of time. Conventional anti-nausea drugs aren't helpful for CHS suffers, but the disorder typically resolves by abstaining and taking hot baths. Here is an article that goes into detail on CHS.

Cannabis can also aggravate certain underlying medical conditions, such as schizophrenia. Your doctor will have assessed your risk of any serious adverse affects prior to prescribing cannabis to you.
