Percocet used for pain relief is a narcotic medication and prescriptions can prevent people from getting high on Percocet without medical reason.In fact, the Percocet high feeling can get you into lots of problems.
I think the formula of the perfume itself decides how fast it will spoil. My perfumes from Britney Spears Curious and Salvatore Ferragamo went bad within a year and a half. The Britney Spears one developed some precipitation and started smelling like alcohol, while the Salvatore Ferragamo just smelled plain weird.
The problem I've been having with the lighter scents is I end up smelling like laundry detergent or cotton. All of the perfumes I have tested, like Gucci Guilty or Taylor Swift's Wonderstruck, are too sweet and heavy, and I really want to be able to have a clean, floral scent.
