It takes weed 2weeks to get out of my system. i smoked meth 8 days ago. would meth it be out faster since weed only take 2 weeks to get out of my piss?

It depends : on the sensitivity of the test. Most people who use cannabis occasionally to regularly take 4 weeks to clear from the urine and heavy users take 6 weeks. The test you are being given may have a high limit of detection where a GC/MS test will pick up much lower amounts. Meth on the other hand usually clears faster But it depends on your metabolism and the sensitivity of the test.
