Hoax - Quite Possibly
It's always important to do what has been stated around here hundreds of times: Research (and listen to your body as well *s*). I, for one, am very skeptical of content that is laden with uppercase and exclamation marks trying to make me believe something. This holds even more true for content that includes any instruction to "pass it on", especially when it says to pass it on to everyone in my address book (wouldn't they be happy if I were totally mistaken).
All that said, I don't dismiss statements of caution simply due to how they are presented, however, I don't immediately dismiss it when someone replies with "it's a hoax".
This "news statement" began in 2000 and was indeed real (a real statment made), at least at that time. It *could* still hold true for those with old meds in our cabinet. Yet, it's important to note the low threat level, especially as compared to the toxins introduced by the plethora of other chemicals we ingest and apply daily (I don't want Alzheimer's in 20 years nor a stroke in 2). It may also be of interest to read the critic's statements.
Decide for yourself (http://www.snopes.com/medical/drugs/ppa.asp - one of many examples) and be wary of scaring the masses, even when not intentional.
