The strip drink works very very well you have to drink it 2 or 3 hours before your test and drink water before and after taking the strip drink also dont eat for 4 hours prior to drinking the strip drink. I swear by the strip drink, I take 2 ua's a week for probation and I have passed well over 20 ua's using the strip and I even puff the night before the drug test and I puff tough too! so if you have the strip drink no worries you can puff as much as you want and I swear to you that if you do it like I said you will pass no doubt about it.
I also just posted a new thread named how I passed 20+ ua's and puffed the night before. read that it explains in detail the steps to take good luck
