I've been reading a lot of posts lately and thought I would weigh in and let everybody know how I successfully passed my test recently. I've been a consistent smoker and knew I wasn't going to pass the test by myself. I thought about getting a buddy to pee for me, but in reality, who truthfully knows where your friend has been in the past 6 months so I wasn't going to weigh my future on someone's pee. So, after a bunch of reading and speaking with people older and wiser than me I was confident enough to try synthetic urine. First, make sure to get a brand that you feel comfortable with and don't pinch pennies, cause it will hurt you in the long run if you do not get the job. You can purchase most reliable synthetic urine for under $30 dollars and get enough to possibly last two tests. Dr. Greens Agent X is what I used and it was $28.50 for a 3 ounce bottle, and the kit came with a heat pack- which can be found at any hardware store, sporting goods store, etc. (Look for hot hands e.g. if you want extra).
The best method I have found, and felt the most comfortable with, was wearing a pair of spandex or 'sliding' shorts. They are form fitting and can hold the bottle tight so you don't have to worry about the bottle slipping out. Most come equipped with a 'cup' pouch where you can put the heating pad which gets uncomfortable and quite hot down there for the boys (or girls), but it's worth it for the bigger picture. I warmed my bottle up about two hours before heading down to the lab, and made sure the temp was good before taking off. Most places, the temperature they test for is to make sure the bottle is 90-100 degrees Fahrenheit.
When you go to the lab, be confident and dress professionally. The lab techs or doctors will be less suspicious if you are dressed the part of someone who they would stereotype as a 'pothead'. I personally was asked to take my jacket off and turn my pockets inside out before entering the bathroom. I also wore a pair of cowboy boots, as a little misdirection. I know everyone doesn't own them, but my master plan was for them to be suspicious of something being in the boots and not my underpants. If they asked me to take off the boots, they'd be empty- maybe too much planning and thinking but I wasn't risking it. And it was my first time so I was a bit nervous to say the least. When I got in the bathroom, I calmly took the urine out and filled it to the line the nurse specified, checked the temp and I was good to go. For safe measure, I was advised by the wise to spill some in the bowl because places will test the toilet water because there is no way someone will piss 2 perfect ounces and stop- logically. DO NOT piss in the toilet. They won't listen for splashing so don't worry about being too good of an actor. Just make sure the temperature is correct, if its too hot dip it very quickly in the toilet but be sure not to let it go down too much because it will take too long for it to warm back up! I've read a lot of people worrying about there being a different color or it having no foam, but don't worry, there is no taste test involved and everybody's urine is different anyway. Doctors advise your pee should be relatively clear, so if they say something about the color simply respond, "I drink a lot of water".
I hope my experience helps, I know it was an extensive post but I was worried about the small details before I tested. Just remember- think cool, calm and collected. Be confident, and toke on.
