I found a perscription for a controlled substance that I thought that I had lost .
I use Walgreens and asked if the perscription for clonopin was still good. The perscription was within a few days of being 6 months old. I was told that non controlled substance perscriptions were good for one year from the date they are written but controlled substances were good for only 6 months and that they would fill it one time since 6 months had not quit lapsed but they would not let me have refills.

Having read so many negative things about Walgreens, is this true?
