Acetaminophen and Ibuprofen are different substances. The recommended dosage of acetaminiophen is 2000mg, ibuprofen is 200-400mg and some prescription forms come in 800mg.

I don't like to be a dick and tell people to use fucking common sense but at least once a month or so it seems we get somebody on here who wants to get high from smoking tylenol or taking motrin, sudafed or cough medicine that contains active ingredients besides dxm. Every time multiple people reply with "No don't do that it wont get you high and/or it could kill you" and yet the person does it anyways.

Research drugs before you do them, it may even take a couple days but don't post on a cannabis-related message board and wait a few hours to see what people have to say and do it anyways. There are other resources including Erowid, Bluelight, the Lycaeum, rxlist.com and Google.
