    if people smoke to release tention then I think it is good as tention itself is a root cause of many diseases and if one can release through smoking then it is good.

    @Asnaf khattak,
    ‘Tension’ is lay man word for ‘anxiety’.Anxiety is due to imbalance between various brain neurotansmitters e.g GABA,serotonin etc.Smoking is an addiction not a treatment.Anxiety makes the patient to use these illicit drugs to relieve his symptoms.This do provide a temporary relief but makes u an addict.I hope u must be knowing the adverse effects of smoking.Here i qoute an example of a cocaine addict,who use cocaine to relieve his tensions.So wht do u think?Is cocaine a treatment or a poison?I hope u got the difference.
