pefectly safe..

personally i hate the taste of it... (maybe it's in my head) besides it takes to long... i posted a guide, to get the most resin outa pipes possible and still be able to smoke it, and not have to sit around forever while the alcohol evaporates...

best thing is, you don't add in anymore chemicals, all it involves is really hot water, your peices, and a coffee filter... (tho i did add a copule of things to make it easier, but that would have absolutely nothing to do with the composition of it all)
