Cheese (recreational Drug)

Cheese (recreational Drug)

Cheese is a heroin-based recreational drug that came to the attention of the media inside and outside the United States after a string of deaths among adolescents in the Dallas-Fort Worth Metroplex, between 2005 and 2007.

Cheese is a combination of drugs, made by combining heroin with crushed tablets of certain over-the-counter cold medication, such as Tylenol PM. Such cold medications contain acetaminophen, the active ingredient in Tylenol, and the antihistamine diphenhydramine, the active ingredient in Benadryl. Cheese samples obtained in north Dallas contained between 2% and 8% heroin, in contrast to the 30% commonly found in black tar heroin. Users commonly take the powder by insufflation ("snorting") rather than by intravenous injection. This mixture is also known as "Tylenol With Smack", by analogy to the Tylenol With Codeine series.
