Smoke Cloud

An invisible cloud
enveloping our surroundings
penetrating every existence
undetected or simply unnoticed
but present nonetheless
it seeps into me, into you
leaving an odor...sickening
cough, gag, swallow
silently curse the cause
knowing there is a solution
or perhaps a few
would a civil war ensue?
is the price worth it all?
the cloud dissipates
but will return again
how long before its end?
