I quit drinking and smoking at the same time and while it did not bother me much to see others drink the secondhand smoke killed me. It was like I immediately became overly sensitive to the smell of it. It used to **** me off to see others smoke too, it gets better. I don't mean to miniMize what youre feeling at all- the anger could even be a withdrawal symptom. I myself used hypnosis to quit, but I honestly only belive that worked because I wanted it to work. I have heard nothing but good things about Allen carrs book, perhaps you could check that out at the library? It's helped tons of people to quit. These are just suggestions, there are tons of options out there, Im sure you'll find something that is a good match for you. As for anger in general, there is always mindfulness practices or meditation, and my favorite; cardiovascular exercise , it will help clear your body of toxins too.
Best of luck,
