Extremely Infrequent Cannabis User Urine Test Question

[Burnt Toast]

I agree obviously no one can give u and exact time frame, however at the same time someone who smokes everyday, and then someone who smokes once a week, and then someone who smokes once a month, and then someone who smokes once in 19 months, they are all gonna test negative at diff times and it would seem the person who smoked once in 19 months would be the first to test negative.

But how long for a person who've smoked only once in 19 months to test negative depends on the person. As I said, each persons body is different.
