The doctor is insisting he be started on an E-cig.....my buddy is willing to try...I'm considering an "ultimate mr. puffer" for the old guy.....I need help friends, what should you buy for an 84 year old man that does not want to quit smoking...he will beg you for cigarettes, throw a tantrum...disturb other at the home....PLEASE...what should I recomend? thanking you in advance
