I used to be a hard smoker, smoking at least 4 times a day 3-4 hits each session. Recently, February, I reduced my smoking to occassional use. I used the last week in March (at the most 5-10 hits total) and then one hit in April and finally one hit at the beginning of May. I just recently started looking for a new job and they have pre-employment drug testing-hair analysis! I guess I really impressed them in the interview because I got a call back only 4 days later. Today, I had to take the hair analysis test and I am wondering if anyone knows what the allowance is for marijuana on this test?! I have been researching it since I had the interview. I have read that they can dedect up to 90 days on the test and that it will be positive if it shows more than 1ng. Does anyone know what 1ng would equal in reference to the amount of smoke ingested? Since February, I have lost 30 pounds and regularly walk everyday and work-out every other day. Any information regarding this would be helpful! Thank you!
