What is the safest of huffing things

>I heard butane and nitrous aren't too bad I have been huffing isopropyl alchol and vinyl cleaner but I want something safer

i hope this dumbass means poppers by vinyl cleaner (and are just a mediocre novelty with psychedelics ime). and i cant even imagine trying to get high off off ipa when 70% drinking booze is painful to smell

Anyway if you need to ask what the safest thing to huff is, maybe huffing isnt for you?
