If by vape you mean ingest cannabis without combusting it, then yes. If you're talking about e-cigs, which could be even worse for you than actual cigarettes, then f**k no. Please stop destroying your body with that crap, if you use it. Most of the flavor chemicals in e-liquid have not been tested (at all) for aerosolization (vaping) safety. They're safe (as in FDA approved) to eat and drink but they are most likely horrible for your lungs (because lungs are designed to breathe air and only air). And the companies that sell these things don't have to put anything about it on their products if they don't want to, which is pretty shady.
