That wasn't a problem in NYS until this guy bought so much. It was actually Bronkaid he was purchasing, but he was cleaning out every store.
A snipet from one article. "of Ontario, N.Y., was arrested by Rochester DEA agents for allegedly buying 406 Bronkaid caplets -- containing a total of over 29 grams of pseudoephedrine -- over a month's time."
He told the cops he was using it for hangovers.
