I'm not a smoker myself, but my father is and his birthday is in a couple of weeks, and I am think of getting him a vaporiser. He is getting older and his breathing is getting worse, but he has proven time and again that he either can't quit smoking, or just doesn't really want to.

At this point I'm thinking trying to get him to change to vaping has to be a better alternative than to continue smoking. He'd never go out and but one himself, so I'm hoping he will use one if I get it for him.

Where is the best place to buy a vaporiser, what ones are good, what sort of nicotine level e-liquid should I get?

He currently smokes (according to him) 10-12 a day of Rothmans Blue.
