An early Bayer aspirin advertisement features heroin as an ingredient as part of an exhibit at the new Drug Enforcement Administration Museum and Visitors Center which opened in 1999 in Arlington, Va.

But it came to be sniffed _ and later injected _ by those looking for a more intense high or a substitute for other drugs, whether it was morphine in 1905 or opioid pain pills like Vicodin in 2015.
