An increasing number of South Florida pharmacies have responded to the national prescription drug abuse crisis by refusing to fill out-of-state visitor prescriptions. 

Bruce Derby, manager of a Fort Lauderdale pharmacy, said that the decision to limit their service to in state prescriptions has caused a 20% decline in sales; a sacrifice he is willing to take to curb pill trafficking.

The stipulations for filling prescription drugs include an in-state id, pharmacies have reserved the right to serve tourists and "snow birds."
