Message-ID: <022309Z20081993@anon.penet.fi> Newsgroups: alt.drugs From: an13187@anon.penet.fi (H-Man) Date: Fri, 20 Aug 1993 02:17:49 UTC Subject: VISINE to beat POT PISS-TESTS pt. 2 I posted a message the other day about using VISINE to cause false-negative POT PISS-TESTS. Well, I came down this morning and found that I was under a viaduct right near the university library, so I cleaned myself off a bit in nearby FOUNTAIN and ambled in for some further research. Here is a review of 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, and it is used as an antiseptic/surgical scrub, etc. The concentrate would have to be diluted appropriately. There are several less concentrated alcoholic sprays and tinctures. I suspect the alcohol would be quickly detected, however.
