Sewers are not waste disposal units. They are designed to carry water, liquid and solid bodily waste.
Blockages can be expensive and unpleasant for anyone affected.
If a blockage occurs in your drain you will have to pay to have it cleared, which could be costly. If the blockage occurs in the sewer it could cause sewer flooding.
So please - think before you dispose of your waste.
