Well, I came down this morning and found that I was under aviaduct right near the university library, so I cleaned myself off a bit innearby FOUNTAIN and ambled in for some further research. Here is a reviewof two articles concerning false-negatives through SPECIMEN alteration with EYE-DROPS and a bit of speculation about how to use this information.Please respond with COMMENTS or CRITICISMS. |--########>-- H-Man -- > The ingredients of Visine responsible for the blocking of the THC test are> given as benzalkonium chloride (a preservative) and the borate buffer.

It comes highly concentrated, andit is used as an antiseptic/surgical scrub, etc. The concentrate wouldhaveto be diluted appropriately. There are several less concentrated alcoholicsprays and tinctures. I suspect the alcohol would be quickly detected,however.
