We always discourage every client from smoking and we encourage the ones who do smoke to enter into a smoking cessation program...ANY program so long as you stop smoking.
Cigarette smoking causes a variety of terminal illnesses. It also causes skin not to heal, fractures not to heal, premature aging, dental problems, and on and on.
Smoking (any kind) also hurts every personal injury lawsuit. It is difficult for any lawyer to convince a jury that your health really matters to you when you're smoking...so please try to stop.
