Will 1 day old urine work for drug test?

Confusing question: Most forensic drug testing requires the person furnish a fresh specimen, often collected under supervision.

I want to catheterize triple lumen catheter to let out all the urine and insert synthetic urine for a drug test, any comments?

I want to catheterize triple lumen catheter to let out all the urine and insert synthetic urine for a drug test, any comments?

Serious answer: As you know, try your best to not use illegal drugs. Seek help if needed
2nd, you sound like you are going to insert the catheter yourself ; I would assume in a nonsterile way. You will increase your chance of getting an infection in your urethra and/or bladder. Not a fun place for any infection.
There could also be possible legal ramifications, talk to a lawyer. Bad idea, don't compound one probl. ...Read more

Many would say you're unconsciously making a cry for help by messing up so badly. Are you? ...Read more

I took 6 klonopin (clonazepam) around 12mg yesterday at 8pm, I was wondering how long it stays in the urine for a drug test. I weigh 143 and 5-11ft, i workout to?

Why: Not a bright idea to take 12 mg of Clonazepam (klonipin)... Seek a counselor, psychologist, psychiatrist, addiction specialist for help. It can take 3 days to clear but detection in urine also depends on if it's a qualitative versus a quantitative test and the sensitivity of the test. ...Read more
