    I think not. The genetic material on cigarette butts has been contaminated because multiple people's excrement is mixed in the sewer.

    The information you give is too sketchy and it is difficult to give a definitive answer. The specific environment in which the sample is needed (e.g., is it a public or private toilet?). How many people used it during the sampling time?

    Where are the cigarette butts? How long does it take to soak? If in the absence of a DNA sample of "someone", it is impossible to be sure.

    In addition, although DNA can be obtained from human saliva and oral cells, it is not guaranteed that it can be extracted from a cigarette butt similar to that of a washed cigarette butt.

I can't see the situation clearly, but there are many reasons for the blockage, such as the septic tank in the community is full, or the septic tank and sewage pipe in the building where you live are not smooth, and there are some things that are easy to clog into the toilet, and there are also unreasonable design of the sewage pipe in your bathroom (the angle is too large or improper, and the trap is not properly installed) and so on!!
