Personally, I'd never pick it up if you never smoked. It is a great way (probably the best method) to quit smoking, but in all honesty, long-term effects are not known. Seriously, I'd find something else to invest hundreds of dollars into that may be more beneficial to your lifestyle.
If you must, you must... but please take @Foofightervapegirl's advice and DO NOT GET ANY ELIQUIDS WITH NICOTINE IN THEM, if you do pick up vaping.
