Actually the acetaminophen is generic tylenol and has no capability to enhance your "high". the quantitiy of hydrocodone is what it really comes down to, and in the case of the Watson 349 5mg pills, they are the lower end of the spectrum. My advice for aspiring recreational users is to either take 4+ 5mgs or get a hold of at least 7.5's or 10's. If you really are seeking an opiate pk popping "high" i suggest percocet or the purest form of OxyContin. And word to the wise: never waste your time with Tylenol 3's. That shits weak.
