Yesterday I got a stomach virus, so far I haven't thrown up but I still have it and am 100% sure its due to me smoking and having a low immune system because of it. I got really sick this season, multiple viruses and this is the last one for the year I want to deal with... (fyi I never got sick before smoking, about once every year or two) I had like 4 viruses already this year. I'm currently using the juul device while I wait for my IQOS to come in the mail (a real tobacco device) I will then get the tobacco I stride for without effecting my immune system.
