To be fair I'm probably being oversensitive to it, but if you want to be technical about it, someone could read your post and think: "I should try street opiates and see if they have an effect on me, and if they don't like this poster, then I am very likely to have ADHD."

Let's imagine for this person, they struggle mentally all the time but can't afford or get to a doctor or proper care, and so this actually becomes the most reasonable test for them to administer themselves.

I understand I'm nitpicking and creating a scenario in my mind doesn't make it real, I just personally would choose to play it safe and at least word things more carefully.

Again I'm not saying you can't day what you said, just that there technically is a non-zero risk to it.
