When my mom got diagnosed with pancreatic stage 4 cancer and I couldn't cope with it and I was already in a drug explorer mindset at the time and I started taking her opioids and I became quite addicted (no she wasn't deprived of any of her medications she was fine). This whole process absolutely was chemical imbalance. Years before in high school I stopped taking all of my ADHD medication and then started spiraling out of control dabbling in all sorts of disassociative and psychedelic drugs. If I didn't stop taking my Adderall in high school I wouldn't have gone down any of that path.
