 [ Symptoms ] as an asthmatic taking the bus a lot i am around 2nd hand smoke so much that my asthma is worsening mask recommendation i want to know if there is a mask i can wear while waiting for the bus when i can not get away from smokers i went online searching and could not find anything all the websites i visited said it was impossible to really filter the cigarette smoke completely so is there a mask that will do a fairly good job maybe i can wear two of those masks at the same time to better help myself thank you [ Disease ] i am very sorry but determining a solution to your concerns would not be possible over the internet clearly you are concerned so my suggestion for you is to see a psychologistcounselor someone with a special interest in sex therapy to properly assess and help you
