Gonna make this brief.

Asking for someone close to me (genuinely).

They are due to have a work drug test next week. Their future employment (a very good job) is based on passing the test.

Said person stopped smoking weed on January 10th so is 63 days clean. However, home test kit is showing weed still present in the system. They have 5 days before the test.

I’ve researched on their behalf and can see no conclusive solution. They are currently taking very low doses of niacin (16mg) which is having little to zero impact. I’ve told them to load up on water and fast for a couple of days before resuming eating 2 days before the test.

Any advice from you guys is greatly appreciated!
