Meth stays in the system for 4 days. There is no way you're going to be able to pass in 4 hours.
I Smoked Methamphetamine 13 Hours Ago, I Have A Drug Test In 4 Hours How Can I Pass?
It takes about 72 hours for your system to rid it's self of meth or cocaine
No way buddy!! Why would you risk taking a drug test knowing you had to pass in order to do whatever it is your wanting to do. That's a shame.
