Smoking - I used to smoke 60 a day, stopped after I go the flu (couldn't smoke for days!) for two years and then celebrated our new house with a cigar. Went up to 25 small cigars a day and then discovered vaping. Haven't smoked a cigar or cigarette for 18 months. No smell, tar or bad things (so they say) and you can gradually reduce the nicotine to zero. You get the hand to mouth thing, something to share with other smokers (or non-smokers, they don't seem to mind vaping). The figures suggest that 75% of people who start vaping quit real cigarettes. Give it a try, it may work for those smokers who have trouble giving up.
