Drug combinations you should never try

This thread can be seen as the opposite of the "drug combinations you like" thread.<br><br>It's mainly focused on sharing helpful advice (what NOT to combine) rather than scaring people with horror stories.<br><br>Please only post actual combinations, not just "drugs and heroin" or "drugs and Weed" - be specific.<br><br><br><br>EDIT: I feel like I need to clarify something in regards to alcohol. <br><br>I know many people won't necessarily see alcohol as a drug, but it definitely is one, I included it in the poll and I'm sure most of you understand what I mean when I say "alcohol". If you think mentioning alcohol in your comment makes your comment less valid or less worthy, I think that's your personal opinion, but it's not my place to tell anyone what they should think and believe, after all everyone has different life experiences and perspectives on pretty much anything.<br><br>The reason I'm mentioning this is that I've been getting some comments like these:<br><br>>kmfsnl<<br><br> catalogue of bad combos: benzo and heroin opiates, stimulants and psychedelics, weed and psychedelics, psychedelics and psychedelics, psychedelics and anything, methadone and stimulants, cocaine and tranks, coke and heroin, coke and xanax, coke and gbl, coke and heroin and xanax, caffeine and heroin, weed and codeine, tranks and xanax, 3 scoops and 5 tabs, etc.<br><br><br>>throwaway62795485<<br><br>Ketamine and anything. Fiorinal and anything. I swear to God I almost blacked out when someone offered me a line of coke w/ my Fiorinal CIII. Like hell I’d taint my fiorinal w/ your filthy coke.
