It seems likely that the concept was originally created as a joke, and after seizures of low purity heroin cut with paracetamol (acetaminophen) "validated" the claims, the DEA issued a warning. Although the source of the original hoax is gone, newspapers and media outlets continue to make reference to each other with no mention of any primary sources, perpetuating the myth of cheese as "starter heroin" for children. However, there may have been some ostension of this legend in 2007 involving a few individuals in Texas.
