I have made a small discovery with my bong,
it has an extra cigarette filter just near where the the pipe is lit,
but that is not the discovery…
onto the discovery….
that when I leave old smoke in the bong it makes me cough,
that when I use up all the smoke from a toke I get no coughing,
but if I have a toke and leave smoke in the bong next time a have a toke it will make me cough
mix new and old smoke it makes me cough
leave old smoke in there, it makes me cough
but take a toke with fresh new smoke , I get no coughing.
Thoughts ?
