so i got this new dealer who i've never bought off before i don't really know him (i met him outside randomly and he showed me all the strains he got with him😭) and his prices for pills specifically scetched me out a bit since it kinda seems too cheap to be true (shi like 3 -4.50€ for xtc). i thought about getting a test kit to test his stuff but the test kits i can get at my local head shop are like for one substance specifically and only show if that substance is in it. that's why i'm wondering if laced drugs/pills with fent or sumtin like that do still contain the drug you originally wanted? because i don't wanna risk as example testing xans or sumtin and taking them because the test got back positive but in reality just like a small portion of it was actual xanax if that makes sense
