Smoked marijuana in jun2013 for 5 days and twice in Oct2013. I have to take a drug test in a week.. Can it be detected in urine or hair follicle test?

Doubtful, but: If the amounts were huge in Oct, the hair test at a very fine cut-off might nab you. Not likely. Here's a link. http://marijuana.com/drug-test/detection-time/ Stay clean since it matters. Good luck. Perhaps someday this will be a thing of the past. One can hope. Till then, one must be smart. ...Read more

How can I pass blood and urine tests after i took a few puffs of a marijuana cigarette? I have been hired to a new job unexpectedly and I have to take test for health and drugs, help!

How can I pass blood and urine tests after i took a few puffs of a marijuana cigarette? I have been hired to a new job unexpectedly and I have to take test for health and drugs, help!

Out of luck: If those few puffs were enough to give you a high, it was likely that it would raise your thc to detectable levels (usually 50 ng/ml). If it was truly a "few" puffs, it is likely that you did not achieve significant levels. However, there is nothing you can do now. Water loading will lower your urine's specific gravity and cause a failure of the test. No internet product actually works. ...Read more

How long does synthetic marijuana stay in urine?

How long does synthetic marijuana stay in urine?

Impossible to know: Synthetic marijuana could be any chemical and/or herb -- so it's impossible to know how long it remains in your urine without knowing specifically what you've consumed. Then, lab standards would have to be developed. Synthetic marijuana is a designer drug -- the makers are changing molecules to avoid laws. Of course this makes it even more dangerous to use. Please don't. ...Read more

26 f, microscopic hematuria detected inconsistently in urine tests. Blood tests show kidney function is fine. Should i be worried/see a urologist?

26 f, microscopic hematuria detected inconsistently in urine tests. Blood tests show kidney function is fine. Should i be worried/see a urologist?

Constant hematuria: If you have no urinary tract infection, you need go to a urologist to assess your urinary tract. You will need a renal ultrasound and probably an intravenous pyelogram to see if there are any problems with your kidneys. If these studies show no problem, you will need to have the urologist do a cystoscopy so your urinary bladder's wall can be visualized to see if you have any abnormalities there. ...Read more
