Heroin drug test question 74 hours after use

[Kazeme]

If a friend of mine has been clean for 45 days... And used 1/10th of a gram at 1 p.m. Friday... Will it be out of his system by 3 p.m. On Monday? He is 6 foot tall and 190 pounds... Aged 25 years old... Let me know please! It's his first probation drug test

Bluelight doesn't allow drug test discussion so I have to close this.
