Not unless they're structured similarly to THC, which they're not considering THC is very unique. I know from first hand experience that JWH-018 doesn't show up.
From personal experience, i know your fine with most synthetic cannabinoids and drug tests, including those found in Spice Gold, Chillin XXX etc. I personally had full access to these products until the shit hit the fan like with many RC's. I was on probation for a year or so, the synthetics never showed up on tests. But no matter how you choose to categorize your synthetics, i still believe that the literal plant material (or marijuana) is still the fullest high one can achieve when it comes to you satisfying your cannabinoid receptors (and CBN and CBD receptors obviously). But synthetics are the way to go if you are getting tested, for sure. <3
hahahaha yeah i'm on probation and i smoke about 2-3 grams a day,honestly huffing gas would make you fail for thc as quick as cannabanoids
