simple abstinence/dilution question

Hey i was wondering if there were ANY reports where people were only clean for 1-2 days and passed with dilution?

thanks

What is your smoking history?

It's been done, but heavy users are not good candidates for that short of clean time...

I have a friend that I have witnessed first hand will smoke the night before a UA and will pass. She is very skinny. Its rare but it happens. Wish I could do that.lol
