Is adderall addictive?

so I have intermitten explosive disorder, and ADHD, but I don’t take meds, and as a joke my brother who also had ADHD gave me one of his aderall pills to see what would happen, and it was like the most chill day I’ve ever had in my life, I was slower to anger and just felt content. Not high, but hard to describe, anyway, since then I’ve been stealing them, I wouldn’t say the desire as of now is too strong, but it’s becoming a problem. I’ve taken my probably 7 or 8 so far. Are they addictive?
