I applied for a job many months ago, which will require a medical including screening for the use of any illegal drugs. I have now been contacted and will probably have to go for this medical at some point over the next couple of months. Incidentally BUPA will be carrying out the medical. Unfortunately for me, a few weeks ago i partook in smoking some cannabis. This was over a couple of evenings, and i have to stress the one and only time for many years, and involved maybe 8 joints in total.
What i would like to know, if anyone can tell me, is how long it will take to get it out my system so it isn't detected. I have heard figures ranging from 3 weeks to never. Also, if anyone can tell me what method BUPA use to detect it. Urine or hair sample?
One thing is for sure though, if i do get the job, random tests are carried out periodically, i won't be touching it again.

Thank you for asking at Ehealth forum!

I read your question and I understand your concern.
Its metabolites are detected in urine and faeces.
It takes almost 2 hr to 3 weeks to eliminate from the body .
I hope it helps. Stay in touch with your healthcare provider for further guidance as our answers are just for education and counselling purposes and cannot be an alternative to actual visit to a doctor.
Take care
