KDMC — youngsters having drug in the sitting area off the ground

I regularly use kdmc ground to jog. And i have found that most of the time in the evening there are groups of boys and girls who smoke drugs sitting there. I have complained it to the swimming pool security staff but there never took any action. They say they are afraid of those youngsters. Government should take serious action against this. Youngsters do this because noone stops them from doing this. If this continues then later our kids might also do this as its not stopped. Expecting a quick and effective solution to this.
