Odds to come positive are very low
i read through your query and i think the odds are less to come positive. here is what you should know
Marijuana do not incorporate to a great extent into hair i want you to know that Hair analysis is not a sensitive enough tool to detect cannabinoids/marijuana. it can also be incorporated into hair simply by second-hand exposure. so i dont believe this test is reliable any more but the odds or coming positive are less in your case.
Cannabinoids can be detected in the urine for as many as 21 days after use in persons chronically using marijuana because these lipid soluble metabolites are slowly released from fat cells into the blood; however, 1-5 days is the normal urine-positive period. so if tested this way you will come negative
Saliva testing is more sensitive and i am sure that will come negative too as 2 weeks is enough to get most of it out of the system.
So in Nut shell. No worries. i believe you are good to go.
Hope i was of help. If you have any more questions to ask please feel free to. other wise kindly close the discussion and rate the answer as per your experience.
I wish you good luck and take care of yourself.
