What is the Islamic legal ruling on taking the drug "Ritalin" to improve concentration, and on practicing the legal profession which relies on laws that contradict Islamic Sharia?

The ruling on the profession of law has been previously explained. As for the drug "Ritalin," the default ruling for medicines is permissibility, unless there is something in them that necessitates prohibition, such as harm, intoxication, sedation, or impurity. Consulting physicians have stated that this drug is not a treatment for absentmindedness, and it is classified among narcotics. It causes euphoria similar to intoxicants and leads to addiction with continued use. Therefore, it is not permissible to use it except in cases of dire necessity.
