As marijuana becomes either decriminalized or outright legalized in more and more jurisdictions, the problem of finding an effective and efficient marijuana test looms over legislators. Thankfully, researchers from Stanford University may have overcome a serious hurdle by inventing a new saliva-based marijuana test.

Previously, marijuana testing was a tricky issue, especially when considered in the context of weed as a legal drug. While scientists and doctors have been able to accurately test for the presence of THC for years, these tests required either a blood sample or a urine sample. Neither of those methods are practical when it comes to a roadside test. The new marijuana test can detect THC in potential users with a simple saliva swab that cops can administer and it delivers results in just three minutes.
