thanks for your answers guys, I guess is really upto me, some can do it, some dont. Im starting to use AVTR now for drug usage and smoking. So far I havent smoke a cigarrete, although, Ive stopped sominking for weeks before, it was normally after getting a horrible flu or something, and I couldnt even smell smoke from others smokers, normally it took me a week to start feeling ok again, so I took advantage of these and quite normally for 3 weeks, then again, for some stupid reason, I came back smoking. Now Im craving like mofo for a cigarrete, specially after eating, but im using AVTR and so far, it works
