I m almost 20 years old and have only smoked intermittently for about a year. I m guessing maybe 10-13 packs over the course of the last year, maybe less. My allergies were worse this summer and I had some difficulty breathing so I decided to quit. Especially since I ve started exercising. I had my last one a week ago. Last night I went to the sauna at the ymca after my workout and they had it too hot and it felt like I was breathing in water because of the humidity so I got out after a few seconds but I couldn t get any air in there. Since that happening last night I haven t been able to stop coughing. Could there have been any severe affects from the past smoking I ve done?
