will be washed away. Otherwise, it will not go down with nature for a few days.

Usually, smokers don't throw cigarette butts into their commode, that's the reason. It's not good to rush.

Because the cigarette butt is too light, it always can't go down when flushing.

It must be that the sewer is blocked, and the blocked place is a little far away, so the cigarette butts will suddenly appear!

Is it that the sewer pipe is not very smooth, it is not completely flushed, and then it is backwashed.

The toilet was broken, and the cigarette butts didn't flush out!

Either the toilet is broken, or you are not flushing, or there is a possibility that the pipe is clogged.

Someone is coming, it must be, I don't scare you.
