Tbh I'm not at all worried about any of the party drugs you mentioned. If you took 1mg of each of those, at the same time you would feel about the same as you do after a cup of coffee (the amphetamines are relevant at that dose, MDMA/THC/ketamine would be deeply sub-threshold). At the nanogram level? Forget it. There's all kinds of crap in everything we eat, drink, and breathe. Dose makes the poison - there's a big difference between a detectable level of something and a clinically significant amount. You'd be better off improving the ventilation in your house than worrying about whether your lettuce has 1PPT of cocaine metabolite in it. Note that all of the above is about the party drugs. I have no idea about what the deal is with the psychiatric meds and hormones. If anyone has knowledge of whether chronic exposure to extremely small quantities of them and their métabolites has clinical significance I'd be interested to know more. I sort of doubt it, but I'd be happy to be proven wrong
