I never check mine, so I wouldn't know. Prior to
vaping it was sorta all over the place anyway. Somedays high, somedays low. Whenever I take it at the store, it is usually high. When they take it at the doctor's office they usually compliment me on how low it is. Makes no
sense to me.
In theory, nicotine being a vasorestrictor,
vaping should raise it. But since most vapers are prior smokers, they probably already have/had high BP.
