OK so I was just wondering why when I snort coke it affects me completely different then everyone else I do it with? It use to not be like this like just just last night I had a ball or 3.5 grams and I know it wasn't just this batch because that is what I've thought the last few times I've done it all from different suppliers and the affects are always the same the people I do it with all get energetic/talkative ect and I feel like sh** literally every time after last night it's clear it's not for me but it used to not be like that until I went about 3 years without doing it I've read that possibly having add could be a factor but there's always someone who posts down the line to completely make me re think any assumptions I come up with that being said please don't post a response like "oh your just getting some bad stuff" or "then why do it" or "ive heard" ect I just want a answer preferably based on some sort of science or personal experience thanks.
