Have you ever heard of the electric cigaretts?? They are really amazing! Ive never been a smoker myself but my whole family and many of my friends are using it. It still has some tobacco in it but it works like the patch where it starts with high nicotine then you can gradually lower it down to 0 nicotine. Its really helpful though because you still get the sensation of smoking because it give water vapor smoke and it has a flavor (not exactly like the cigs from what I understand, but still something) and it satisfies the hand to mouth fixation. :)
I highly reccoment it just from the success Ive seen it have on multiple people!!!
There are many different types out there but my man was able to find his for $40 for 2 and there is a little bottle of refil liquid that costs about $15 and it is the equivilent of like...150 boxes, if I remember correctly.
Good luck to you!
