The relationship between migraines and cyclic vomiting syndrome isn't clear. But many children with cyclic vomiting syndrome have a family history of migraines or have migraines themselves when they get older. In adults, the association between cyclic vomiting syndrome and migraine may be lower.

Chronic use of marijuana (cannabis sativa) also has been associated with cyclic vomiting syndrome.
