i apologise if this has been posted before, but i open this thread only occasionally, to see if there have been any real developments, and it seems that apart from ingredients from insecticides, not much else.
many foreigners tend to want to experience "real" thai culture, and get involved with the locals and their crap on their first visit to thailand.
well. the wonderfull locals often make their own illicit alcohol, and to get in the swing of things, many people would/could be coaxed into getting into the spirit of things and joining them .
i am not trying to say that the deaths were caused by imbibing illicit alcohol, but here's a thing:
often, insecticides are added to these brews, especially in the form of the locally available and very toxic "polydol" (don't know the ingredients but i remember reading the label and being shocked at how casually and liberally the stuff is used in most thai households)
the polydol is added to get them on a buzz quicker, and since most asians cannot manage too much alcohol before passing out, a westerner drinking this stuff would possibly ingest far more.
if insecticide was a cause, this could possibly be a way it entered their systems- not skin contact or inhallation, not malicious poisoning...just simple thai sinook!
advice to anybody visiting thailand:
keep your distance from the locals
don't drink with them
don't dine with them
don't party with them
don't sleep with them without protection.
