if youre serious, itd actually help reduce overdose deaths. fent is in everything now so if they get regular heroin they wont od on fent. but realistically its probably too late. theyll just take a shitton of heroin to make up for it not being fent, and theyll od anyways. you could try those official facilities where they do the drugs there, but i think those only work in white countries, not ones with a lot of niggers and mexicans.
