Proof of what? That addictive chemicals are addictive even if a person has adhd? It’s point blank stupid to think otherwise. Feel free to search online and see things saying that when used as perscribed at low doses adhd medication doesn’t typically result in addiction. That isn’t saying the chemical itself is somehow different, or that people with adhd are somehow immune to addiction. People with adhd can abuse stimulants just as easily as anyone else can.
