I am here to tell you that many, many
people have stressful situations and they don't smoke. Using the stress level is a crutch and you're justifying your usage, and that's ok if you aren't going to quit. The fact is, the decision to smoke is yours.... you can choose to smoke or choose to not smoke. Help is available, but you have to want to quit, and you have to want help....
Stressful job, bills piling up, student loans, debts....
