Thank you for the advice.....I am 200 lbs haven't smoked for 16 days won't test for at least 5 more days....but I have smoked for 15 yrs. & I tested my self yesterday & I am positive....so I think the synthetic is my only choice.
I have been there & passed a test two years ago & it was urine test (its a small medical building). With synthetic....but they barely took it cause of temp.

2 Questions

1. When you say practice should I only practice heating to 90+ or should I practice with a sample & the entire process....another kit is not too much...I just don't trust the heating pad cause the place is 40 min away.

2. What do you think the likely hood of a place like that changing its proceedure of testing
