Home drug tests and how long does marijuana stay in your system for?

I'm going to buy a couple of those home drug tests from walgreens so that I can test my girlfriend over the next few months to see if she really is being honest about quitting, she's lied before, if she is truthful I'll marry her if not I'm done with her. So my question is how accurate are those tests, and how long would it take for marijuana to be out of her system before I start testing her?

it can stay in your system 6 weeks
Sounds like the relationship will not work, since you have some serious trust issues.
its stays in your system for a couple months but not exactly sure how many
ive passed them easy b4 ive smoked 1 day the next day drank alot of bottled water and then took the test the day after and passed there not good
Why does it matter that she smokes pot?
If she has smoked it within a couple months she could test positive for it on a test.
