Practice indoors. Pop your jaw while you have your lips formed in a big circle. I quit smoking cigarettes, and thats one thing I miss. Also eating a big fat meal and smoking a cigarette after.

But overall, fuck cigarettes, you could buy a quarter of some dank ass weed at the end of every month, and you don't wake up feeling like shit everyday. Dont let them tax you on something that makes you feel like shit, and is terrible for you.
