If by benign you mean potentially teratogenic, then sure, nicotine is benign. Furthermore ecigarettes don't contain pure nicotine. They're unregulated and they might contain other chemicals that make them dangerous in other ways than real cigarettes. And using nicotine to get a similar reaction in your body as caffeine? Isn't that like using a gun to kill a cockroach at your feet when stepping on it would serve the purpose? Just give me my coffee.
