Tests on the pills, known as "London Underground", showed one tablet containing BZP, but another with a compound found previously only in a Bulgarian cough suppressant.

People have suggested Glaucine (poppy alkaloid) as the talked about compound. [E.g cough suppresant called Glauvent]

[Acute glaucine syndrome in the physician's practice: the clinical picture and potential danger]
The author describes a clinical symptom complex which appears in some patients as a central nervous system side-effect of conventional doses of glaucine, a non-narcotic antitussive preparation, used in outpatients; the symptom complex is described by the author as acute glaucine syndrome (AGS). Clinical manifestations of AGS are the following: 1) very prominent fatigue, which occurs acutely after taking a conventional dose of glaucine and making any kind of professional activity impossible at the moment; 2) very prominent sleepiness, which occurs acutely together with fatigue and is always combined with it; 3) unusual clear but somewhat estranged perception of the environment: the patient sees and understands everything and is oriented well enough, but cannot take a clear and adequate action, 4) full recovery of the impaired functions after the drug is discontinued; 5) AGS recurrence after the drug is taken again. The hallucination-like effect of glaucine, described earlier by the author of this article, which is manifested by bright and colorful visual images, may be considered a facultative AGS component. The author stresses a potential danger of AGS development in persons who control moving mechanisms or vehicles and adduces some clinical observations. PMID: 17243616

Experience quoted from another forum:

I have tried it. I took 150mg and felt a content feeling similar to kratom. And everything became very colorfull. With slight visuals that reminded me of mda. The experience was definitely not as strong as codeine or morphine. Maybe in higher dosages it may give more interesting effects but it's not really worth your money if you're gonna do 150mg and I don't know if higher dosages are safe. It also kept me up all night as I was trying to sleep.

I found it to be enjoyable.

Anyone have any further information to add? Sounds a very strange compound to use.
