I was a hard-core smoker and at a point of time,  smoked around 15 cigarettes a day,  and smoked almost 12 joints a day,  for past 7 years.  Each and everyday. I recently started having breathless nights and breathing problems, but only at night. So I quit smoking cigarettes and joints. It's been almost an year and a half since I quit cigarettes and 2 weeks since a quit joints.. Still the cough is persistent and heavy and it sucks.
