I recently just took a pre-employment drug test for a new job . I was a little nervous about using someone else's pee but I didn't have much of a choice . Either that way or not get the job . I smoke a lot so I was very skeptical about using any detox drinks . I had an interview Friday and the next day Saturday I had to take the pre-employment drug test (did a bomb as* job with the interview). So I did alittle research for successful results using someone else's pee . I read about the condom , hand warmers , heating pad but I did none of those . I had my brother gf(super clean pee) pee in a cup , that I poured into a medicine bottle (regular size ) and then microwaved it for 10 seconds (not to hot) and checked the temp which read 101, immediately I put in in my bra under my boobs (I Have pretty big boobs) so it wasn't to hard to hide and there is plenty of body heat and coverage there. If you are worried about it showing through your shirt wear a long sleeve and put it between your under arm and boob. So I drove to the lab which was about 30 mins from my house . Before going in to take the test I used a 3 dot thermometer ( I think those are what is called or the plastic thermometer) and the temperature read 98 so I knew I was okay . (Temp has to be between 90-100, which isn't that difficult to maintain being that your body heat is keeping the pee around that temp. So I went to the lab , luckily I had no wait time to start the test . The lab tech taped the sink and put blue liquid in the toilet . She told me to put my bag in the room and I only had 4 mins and do not flush . So as soon as the door was closed I got the medicine bottle from my boob and poured it In to the cup that was given and the remaining in the toilet . The temp on the cup was perfect (I believe 98 I gave the tech the cup and the first thing she did was check the temp and I was good to go. I am currently waiting for results but I know as long as I pass the temp portion for the pee test then I am fine . Good luck . Don't be nervous like me . Just act natural . The things you have to do when you can't put the weed down lol .
