Will a one-time use of marijuana show up on a hair test?

Question

I just found out I have to take a hair drug test for a job. The last time I smoked was around March 3-5 this year, and since it was in England it wasn't very strong and I didn't get high. Also, my roommates regularly smoke and I've hung out with them while they've done it, but I never smoked with them. I have to take to take the test ASAP, so please let me know my risk of testing positive. I understand that I shouldn't have done it in the first place/shouldn't be around my roommates when they smoke, so please don't leave me any messages to that effect. Thank you!

Answer 1

it  has nothing to do with hair, so probaby not

Answer 2

It goes after 3 weeks max. It only remains in your blood for about 4 days.

Answer 3

I'm not sure, but just don't take the risk.

Answer 4

Short answer: Yes, it'll show up.

BTW, don't try shaving your head to avoid the test...you have other hair too: armpit, pubic, eyebrows, etc.

Answer 5

I really don't think it will show. I had two tokes a week before a test once and passed. They do have special shampoo they sell at head shops you can try. I don't know if they work or not.

Answer 6

get someone elses hair to be safe

Answer 7

If you haven't smoked since early March you'll be fine.

And don't feel guilty!  Rock on Dude!

Answer 8

I think hair tests come up positive even if you are around the smoke.  But I'm not sure.  but if it was like 2 months ago you dont still have it in your system.

Answer 9

I think you'll be ok... second hand marijuana smoke can't get you high... and one time smoking should be ok... if you're worried drink a ton of green tea... or go to the GNC and buy their cleansing tea.

Answer 10

i dont know for sure but i would say that there is a risk. hair tests really suck compared to the others. you may want to consider going britney style lol

Answer 11

YOU ARE NOT PASSING THE HAIR FOLICLE TEST! IF YOU HAVE LOOKED AT WEED IN THE PAST YEAR , YOU AREN'T PASSING IT. DOESNT MATTER HOW MUCH U HAD OR HOW STRONG IT WAS, YOU CANT PASS A FOLICLE TEST. THERE ARE NO TRICKS. IT'S IMPOSSIBLE. SORRY.

Answer 12

marijuana stays in your system for upto 28 days. if the last time you smoked was early march you will be clean. as for hair test haha isnt that going abit too far? even if you was found positive couldnt you blag it like say you was on a bus and someone smoked a joint? good luck hope the job goes well.
