It’s high time peo­ple knew more about the coun­try go­ing to pot

The China Post - - TV & COMICS -

DEAR AN­NIE: For many years, I have heard about the dan­gers of sec­ond­hand smoke. I am a non- smoker, but was mar­ried to a smoker for 13 years and have asthma.

Now that pot is be­ing le­gal­ized in some states, in­clud­ing where I live, what are the dan­gers of sec­ond­hand pot smoke? I haven’t heard a word about it. Are the states just look­ing for ad­di­tional tax rev­enue and keep­ing it out of the news? — Con­cerned Breather in


Dear Breather: Ac­cord­ing to the Amer­i­can Lung As­so­ci­a­tion, in­hal­ing smoke is harm­ful whether it’s from cig­a­rettes, pot or burning wood. Mar­i­juana smoke con­tains many of the same tox­ins, ir­ri­tants and car­cino­gens as tobacco smoke, and pot smok­ers gen­er­ally in­hale it for a longer pe­riod of time. Sec­ond­hand mar­i­juana smoke con­tains the same in­gre­di­ents.

How danger­ous is it to non- smok­ers? A 2014 study found that blood- ves­sel func­tion in lab rats dropped by 70 per­cent af­ter 30 min­utes of ex­po­sure to sec­ond­hand mar­i­juana smoke and hadn’t re­turned to nor­mal even af­ter 40 min­utes. And the rats suf­fered the same ef­fects even if the pot con­tained no THC. So, you might not get a “con­tact high,” but with con­tin­ued ex­po­sure, you could suf­fer im­paired lung and blood- ves­sel func­tion.

Mar­i­juana is much stronger to­day than it was 40 years ago. More stud­ies need to be done, ob­vi­ously, but if you are reg­u­larly ex­posed to smoke of any kind, you are likely to de­velop a prob­lem. Steer clear.
