No.
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.
What if you smoke marijuana a month ago but you only smoke one time would it show up on your hair drug test
show up where?
Smoking and/or eating the marijuana plant, or coming into contact with the drug THC. There have been some who say that a faint line will show on the test if you inhale marijuana smoke second hand.
if enough resin was burned in the process, then yes it will show up on a hair follicle test.
Possibly yes. My advice is to never NEVER use drugs or smoke. If you knew the bad and terrible stuff that marijuana can do to you then I would recomend for you not to use marijuana. I shouldn't even explain to you how bad marijuana can do to you or possibly....kill you.....A standard hair test goes back 90 days, but they can go back longer. It is possible for second hand smoke, either because you inhaled or because it got absorbed into the hair, to cause a positive result.
any amount of marijuana smoked will eventually show up in the urine.
yea so dont smoke it
yes it can be a false positive.
I'm assuming you mean "will THC show up on a urine test from a contact high?" (meaning you didn't actually smoke, you were buzzed by "second-smoke") to which the answer is NO. A contact high means you have less than 5% of the THC from the entire sesh in your system.
No.
The traces of Marijuana remain until the hair falls out or you cut it off.
