Sick Leave Applied to BackDROP?

I understand that unused sick leave may be applied towards retirement for the number of years/months worked. Can that sick leave be applied towards Back Drop? For example, if a person has six months of sick leave, can that individual only work 18 months and then apply the six months of sick leave to obtain a two year Back Drop?

No. You will get one month of credited service for each 168 hours of unused sick leave you have at retirement. While this will increase the amount of your benefit, unused sick leave cannot count toward eligibility for retirement or as part of the BackDROP period. That is, the months of unused sick leave will not make you eligible for retirement (or BackDROP) sooner, but will increase the amount of your payment.
