Question : I have been clean for awhile I got a gram of meth. We use it recreationally. Between two people I intravenously used it so I would guess I used a half of gram myself. So my question is I have a dot drug test Monday am. I did it on Wed. Will I be clean? How can I pass the test

Detailed Answer:
Hi
Welcome
I have gone through your query.

Methamphetamine’s high lasts anywhere from 8 to 24 hours, and 50 percent of the drug is removed from the body in 12 hours; Methamphetamine will stay in the plasma between 4 to 6 hours; it can be detected in the urine one hour after use and up to 72 hours after use; Methamphetamine metabolites can be detected in the body for 2 to 4 days.

Time to leave the body = 2-10 days. Generally, the heavier the user, the longer it will take for meth to leave the body.
Hope this helps
Take care
