Answer: This depends on what type of test they use. If they use a sample of your hair and you have not cut it since your last use, then it is possible that it will be detected. If it is a urine text (most likely) there is very little chance that it will come back positive as methamphetamine usually remains detectable in the urine on the order of days. That being said, heavy use and other factors like kidney function can impact the length of detectability; however, it would be very unusual to have a positive urine test after 1.5 months of abstinence.
