I know exactly how you feel, I was in a very similar situation. I remember that I was so nervous at that time and I took it out on everyone around me. I didnt know what could I do until, thanks god, I found Smoke Deter. Now I can look back and laugh on myself and in the same time I remember how helpless I was. I hope that I'll never be in the same situation again

    The poisons and toxins in the smoke and tars actually kill lung cells. This progressively increases the size of the alveoli, decreasing the area available for gaseous exchange and this is called emphysema.

    The lungs try and repair and protect themselves producing excess mucous, the damaged cells and mucous form a nutritious broth for bacteria and repeated infections occur, doing more damage in an increasingly destructive cycle, this is COPD.

    It coats the healthy lung tissue with "tar" and "nicotine" obstructing the normal function of the lungs.

    Smoking damages the airways and destroys the air sacs in the lungs.

    COPD is a mixed disease containing the components of chronic bronchitis, which results from the linings of the airways being swollen and producing an overabundance of mucus and bronchospasm, which is what takes place in asthma. COPD may also have components of emphysema.
    All of these actions can restrict or block the airways making breathing extremely difficult.

    Emphysema, which may be present without chronic bronchitis or bronchospam, is the result of destroyed air sacs in the lungs. This causes them to lose elasticity and their ability to expand and contract normally (as what occurs in normal respiration).

    Although both conditions are, at present, incurable, stopping smoking can slow or arrest progression. Some cases cannot be traced directly to smoking although the great majority of people affected with either disease have a history of or are current smokers.

    Possiby because filling your lungs with smoke and the residue from it causes you to cough – it can then progress, the cough worsens and, hey presto, you end up with bronchitis. As for emphysema, I’m not sure but I guess that lungs which have been damaged by coughing and smoke are simpy more susceptible to infection and illness.

    80% of COPD cases are caused by smoking. In short, smoking damages the lining of the airways. Inflammation is the bodies natural response to damage, however inflammation stimulates the damaged lining to secrete excess mucus and causes the airways to constrict.

    Tobacco smoke contains harmful chemicals and toxins, which when inhaled, settle in the lungs. Prolonged exposure to tar in cigarette smoke leads to the narrowing of the bronchioles and destroys the lung’s protection/ filter system.

    COPD does not happen over night, it is caused by prolonged irritation of the lungs.
