To provide a peel assisting pasting material capable of safely discarding an adhesive sheet by peeling the adhesive sheet from the surface of an adherend without touching the adhesive layer of the adhesive sheet.

The peel assisting pasting material has the 1st adhesive layer on at least a part of a surface of a sheet substrate and the 2nd adhesive layer on the remaining area of the surface. The 1st adhesive layer and the 2nd adhesive layer account for essentially the whole area of the surface of the sheet substrate. The 1st adhesive layer contains a reactive compound reacting with a legally restricted drug and eliminates the drug effect. The size of the 1st adhesive layer and that of the 2nd adhesive layer are larger than the size of the adhesive sheet to be applied to the adherend. The adhesive sheet can be peeled off from the adherend surface by using the pasting material.
