Before I make my own ejuice I thought I should ask if there are any "professional" flavors on the perfumers apprentice website that are not safe for ejuice? I know some flavor concentrates can have chemicals that are not considered safe for vaping so I want to be certain before I go ordering flavors that none of them are known to be dangerous to inhale. Thanks!
