How Long Will Thc Stay In Your Hair
Marijuana and hair: 90 days.Get a more detailed answer ›
I have a upcoming drug test, how long does marijuana (thc) stay in your hair follicles? An is there anything to take it out of your system?
Depends on several: things - how quickly your hair grows and how often you have it cut. It stays in the hair as long as the hair exists - essentially forever. However, if your hair grows at about 15-18 mm per month (about 1/2 inch) and you have it cut every 6 weeks, the marijuana (THC) deposited from one smoking episode would take a half year to get to the ends of your hair where it would be cut. ...Read moreSee 1 more doctor answer
How long does thc weed stay in your hair if you've only smoked once or twice 22 yrs old 162 pounds male?
A long, long time: depending on how long/short your hair is. When you use many drugs/chemicals, the blood supply to the hair follicle deposits that chemical into the hair being made at that time, and that tiny "band" of positive THC (or other drug) will then grow out with the hair. If you never cut your hair, it will always be there, but with average hair growth and average rate of cutting, it will be there months ...Read moreSee 1 more doctor answer
How long will THC stay in my hair if I smoked once in July on the 18th. It was my first time ever.
Curious question: Hair grows at a rate of about 1/2 inch a month, and thc that is deposited in the hair will stay in the zone that represents use while it was forming. Remove the hair to below the that level and it would not be found on hair analysis. However, most do not assess hair to detect it, they use urine.This can clear in a week or so if use was minimal. ...Read more
Depends..: Chronic use may show positive results for months. It depends also on the length/amount of hair tested and the nature of the test being used. Check this link for more details. http://www.ncbi.nlm.nih.gov/pmc/articles/pmc2274831/. ...Read more
Different answers: I have read that one time use might not even show up. Most answers say that if use is regular, then it will stay for about 2-3 months. One person said that his parents, both of whom are police, told him that it could stay for a year. Hair grows at 0.5 inches per month, so they usually cut off three months of hair growth (1.5 inches) for the sample for detection. Why not just not use the stuff? ...Read more
How long does it take for THC to get completly out of your body so you can pass a drug test, hair or urine test.
I'm not wondering how long THC stays in hair,,but I'm curious as why it stays in the hair follicle longer than blood or urine?
Hair stays: thc stays in the hair longer than in the blood and urine. This is because the blood is constantly being filtered (cleaned) by your kidneys and the urine is regularly eliminated from your body and replaced. Your hair, however, does not get filtered or replaced, so the thc remains. ...Read moreSee 3 more doctor answers
My husband has not smoked pot in six months. Will he be able to pass a hair follicle test for THC or must he wait longer?
How long does it take for hair to grow THC free, after last marijuana use. I have to pass a hair test in two months. Heavy user, fast metabolism?
No: Hair tests don't tell when you last used it. It will be accurate for regular use of Cannabis but does not measure current use, but rather non-psychoactive residues that remain in the hair for months afterwards. It takes 7-10 days for Cannabis residues to appear in your hair. In one study 85% of daily users tested positive for marijuana, versus 52% of occasional smokers (1-5 times per week). ...Read moreSee 1 more doctor answer
