I was reading this from Drug Testing Tips - NORML Now I believe norml.org to be a reliable site when it comes to information. Previous to this I have never heard of using Visine to pass an urine test. Have any of you here used or heard of people that have used this technique and what results have they gotten? Using adulterants seem to be an easy way to remain using and still pass. This link contains a lot of good info as well: How to Pass a Drug Test Tutorial - Beat a Drug Test With UreaSample.com - AFFORDABLE CLEAN URINE SAMPLES Im reading that link and it says I can dilute my sample heavily with water. The test I'll be taking is an OTC at home EMIT test so I'm not worried about the temperature. If it was a lab then I'd be worried. So lets all share some stuff we can spike our urine with.
