Legal drugs are mostly used for medicine while illegal drugs aren’t
People may use illegal drugs because they are stressed, depressed, divorced, in pain, or just crazy
You can tell if someone is using illegal drugs by if they are abusing others, having declining grades or struggling in school, having a poor work performance, changes in physical appearance, altered behavior, drastic changes in relationships, having a noticeable lack of energy, spending more money than usually, having issues with financial management, changes in appetite, and more.

No I would talk to him or her and if it keeps happening end it
