It usually isn't tested in such a way as to determine how long ago it was smoked. It could be narrowed down to within a few days if there was a need to do so.

Will marijuana show up in your hair drug test on April 30th if a friend smoked marijuana once around Thanksgiving?
If you did not smoke any marijuana, and you have since washed your hair, you will have no marijuana in or on any of the strains of hair on your head, and it will not show up on any drug tests.
If you smoked marijuana two months and 24 days ago will it show up in a hair sample drug test?
Yes. THC stays in your hair until you cut it off. The THC will show up in your hair for a long time, until all the hair that was on your head the last time you smoked has completely grown out and been cut off. Hair grows at about 1/2 to an inch per month, so if your hair is longer than 2 inches, you will still test positive for marijuana through a hair sample.
You smoked one hit of marijuana you were clean for over a year before that will this show up in a hair or urine test?
probably in a hair test but not in urine

How marijuana do you have to smoke for THC to show up in your urine?

Your friend smoked marijuana one time will that show up on urine sample?
That depends on how long ago you smoked it.
Will THC show up in your system if you had not smoked marijuana?
THC shows up in your system no matter how you ingest marijuana.
Will marijuana be in hair if smoked once?
It depends on how long ago it was smoked. If it's more than a week ago, you should be ok for a urine test. Marijuana does store in your fat cells though, so maybe other kinds of tests could find it.
