Usually I get hit every couple months but I still think they are not truely "random". I'm always opening my fat mouth when somebody starts debating the drug war.And I'm sure the boss knows I smoke.
I have a bag I take to work that has my quickfix kit and it stays with me all the time.My drug tests are done about a half mile from work with a nice little convenience store in between so I just pop in there get me a cup of coffee,pop the quickfix in for 10 seconds in the microwave and go across the street to take my test.I also keep a small digital thermometer with me in case the Urine gets a little out of range of the temp strip then I know which way to go.If its high blow on it after its in the cup if its a little low(lord forbid) I rub my finger and thumb together briskly and touch my thumb to the temp strip to get the temp up.I thnik it wa stinky that taught me that little trick.imp:
