Yes you can. My girlfriend got her asthma because her mother was always smoking around her. Her mother doesn't smoke any more, but my girlfriend will use her inhalor three to four times a day. No. Asthma is not "caused by" smoke, animal dander, pollen, etc. Those things may trigger an attack, but they are not the reason you have the condition. Yes and no. Asthma is hereditary in the way that some people are more likely to get it than others. Second hand smoke is both a trigger for an attack AND a factor that can lead to asthma, especially in young children. Asthma can be 'caused' by certain triggers, but that depends on your family history.

No you cant get asthma from second hand smoke. There are over 40,000 triggers for asthma and has been found in children is being around passive smoke lowers incidences of asthma and heres why.

The inconvenient truth is that the only studies of children of smokers suggest it is PROTECTIVE in contracting atopy in the first place. The New Zealand study says by a staggering factor of 82%.

"Participants with atopic parents were also less likely to have positive SPTs between ages 13 and 32 years if they smoked themselves (OR=0.18), and this reduction in risk remained significant after adjusting for confounders.

The authors write: "We found that children who were exposed to parental smoking and those who took up cigarette smoking themselves had a lower incidence of atopy to a range of common inhaled allergens.

"These associations were found only in those with a parental history of asthma or hay fever."

They conclude: Our findings suggest that preventing allergic sensitization is not one of them."

This is a Swedish study.

"Children of mothers who smoked at least 15 cigarettes a day tended to have lower odds for suffering from allergic rhino-conjunctivitis, allergic asthma, atopic eczema and food allergy, compared to children of mothers who had never smoked (ORs 0.6-0.7)

CONCLUSIONS: This study demonstrates an association between current exposure to tobacco smoke and a low risk for atopic disorders in smokers themselves and a similar tendency in their children."

In 2008 this paper was produced in America and concludes that nictotine and hence active smoking and passive smoking leads to less asthma. It also gives the aetiology (causation) why nicotine and the biologial process that reduces asthma in recipients.

The results unequivocally show that, even after multiple allergen sensitizations, nicotine dramatically suppresses inflammatory/allergic parameters in the lung including the following: eosinophilic/lymphocytic emigration; mRNA and/or protein expression of the Th2 cytokines/chemokines IL-4, IL-5, IL-13, IL-25, and eotaxin; leukotriene C4; and total as well as allergen-specific IgE. unequivocally show that, even after multiple allergen sensitizations, nicotine dramatically suppresses inflammatory/allergic parameters in the lung including the following: eosinophilic/lymphocytic emigration; mRNA and/or protein expression of the Th2 cytokines/chemokines IL-4, IL-5, IL-13, IL-25, and eotaxin; leukotriene C4; and total as well as allergen-specific IgE.

second hand smoke is dangerous because 85 percent of it is side-stream smoke. This means that 85 percent of it is unfiltered, which can lead to asthma, cancer, and respiratory illnesses.

Second-hand smoke has been shown to be a cause of problems such as asthma, other respiratory complaints, and cardiovascular events including heart attacks.
