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.
A fragrance is a smell, usually a pleasant or sweet smell. Often perfumes are called fragrances. If you like the fragrance of coffee, you like its smell. Unlike the word odor, which usually means a bad smell, fragrances are usually good smells. People love the fragrance of flowers and good food. A specific smell can also be called a fragrance.
