Maybe I’m overly sensitive, but I’m really tired of ADHD ableist jokes like this one. With the controversy and struggles of medication for ADHD, implying that the only functional ADHD brain is a medicated one just frankly sucks.
Yes, I would suggest in this specific instance you are.

Not once did I mention ADHD which is a medically recognized condition. However, the use of Ritalin in today's society is not limited to those that are prescribed Ritalin as a treatment for ADHD. There are many many people that use it recreationaly. Being around people using it as an upper gives me the impression that I'm stuck in molasses with their hyper-everything. It's exhausting.
"Needs to up their dosage" would imply someone who medically requires Ritalin to treat something, which could only be ADHD. Take that part out and the joke is otherwise fine/about what you're saying.
However, anyone familiar with recreational drug use knows there's a common phrase of "know your dosage" right along "know your dealer". Yes, it's borrowed from else where, but it's still a thing. Do I need to eat half a bar, or take 2? I might suggest Wolf Of Wall Street as an example of knowing one's dosage.
Taking "too little" Ritalin recreationally — i.e. not meeting the threshold dose — doesn't result in ADHD-like symptoms.
Unless, y'know, you have ADHD. In which case it's not "recreational usage", you're just self-medicating.
People taking Ritalin when not prescribed to them by a doctor do not care about ADHD-like symptoms. They are using it purely as an upper. "To help them concentrate" or whatever they tell themselves. It's less "trashy" than meth, easier to find than coke. The affects are also different than these other drugs.
Besides, pointing out ableism isn't an accusation. In fact, I don't accuse you of anything personally, I bemoan the joke. In the face of this, you retreat to a scenario where you are besieged every day by recreational Ritalin users in order defend your ego from maybe admitting your joke wasn't actually funny (or accurate).
