Drug Test Tomorrow!! Please Help

I have checked for answers to the following but most of the info on this site is old and I just needed reassurances.

I failed my last test at the end of last month but have been given a second chance and have another test tomorrow (was supposed to go today but have a couple of days window). I gave myself a test this morning and found that a month after my last smoke of weed I still failed it (I was a 3 or 4 joint per weekend user). I drank 2x16 oz of Max Strength Test Pass drink that I bought off a site that was mentioned on this site and followed all the instructions. I waited, and pissed a couple of times, the 90 minutes as directed. I then tested myself again and failed again. This is why I decided its best to wait til tomorrow. BTW that stupid drink just induces diarrhea...severe diarrhea and turns the piss to a florescent yellow. I would be suspicious of that if I was doing the testing!

I have decided to use the substitution method but the person I am getting the piss from had taken lorazepam last week (0.5mg). Will I be ok to use this sample?

Thanks

To avoid any potential hassles with the Medical Review Officer (MRO), you should use a urine sample that is totally drug-free. That includes scripted and OTC meds.

Thanks for your reply BT

I got news today that everything went well and I start the new job on Tuesday!

To anyone reading, forget the 'special' detox drinks, pills etc. Substitution is the only way to go and it's easy and stress free. As Burnt Toast said, just make sure the sample comes from someone totally clean. I took a chance with my buddy but it paid off!

Good Luck!!
