I used to think people didnt know I used but they do and they did. Especially my mum.
When ive been using opiates she would know because I often get in fits of anger but when sober I am the most laid back person ever. Opiates change my personality hugely. I also lose weight, get track marks, nod out uncontrollably, not leave my room for days at a time(except to score), not eat and one of the biggest things was that I fucking always used to nod out on the toilet(for like 20 minutes, I could never piss standing up, it took too much concentration in that state) and end up falling off it and hurting myself. Its pretty much impossible for me to do opiates without someone findinng out and me getting myself dependent and in trouble. Also my OCD becomes ridiculously bad, it makes doing normal things in life extremely hard because im worried about EVERYTHING, OCD is no joke.
With meth I just get really skinny and my mood changes. Ive never been too psychotic to the point that it really bothered me, just basically Depressed, Anxious, OCD. I pretty much just be an asshole to people and act at a maturity/intelligence level below my true self.
I never really had any problems with anything else, when I was younger I did a lot of E pills and that messed with me then and people knew it but I dont do E hardly at all these days, not my thing really.
