Hello, SWIM has recently been searching the web for research chemical sedatives that he can use while being drug tested twice a week every week. He likes opiates, but has found little evidence of opioids that can be used without triggering positives on a urinalysis, and even more likely with lab tests. He usually just pisses into a cup test twice a week, but if there is suspicion of use, the cup test gets sent off to the lab for further testing. So just to be safe, SWIM is searching for the perfect downer that wouldn't be detectable in any setting. If someone does know of a rc downer (which it seems like there aren't many) that only passes on a cup test but not a lab test, still please let SWIM know.
