Just did my first Manske tek and I have some nice goop drying which I am excited to try. I have no problem orally ingesting a little salt and vinegar but I want to know if the combustion products of NaCl and acetic acid are safe to inhale, aka smoking a somewhat-poorly extracted manske tek.

You need to convert them to a freebase before smoking. I made the mistake of adding some from a manske to some Changa and the results were less than satisfactory.
