How do you know if your coworker could possibly be on drugs

lately she is very confused about simple tasks that she’s been doing for over two years. She is showing an awful lot of confusion in conversations, and just not following along with directions. This is definitely something new that’s come on in the past couple of I months.

I’m asking you guys because I have never met anyone who does drugs so I don’t really know what to look for

This could be from stress or other problems in their personal life including a change in or new medications, minor head trauma or injury (a head injury from a fall or accident), emotional disorders. stress, anxiety or depression, alcohol or drugs,
Vitamin B-12 deficiency, brain diseases, a tumor or infection in the brain, sleep Apnea, and a lot of other things not obvious to the passerby/coworker.

Really, the best thing would be to talk to her in private... you know, pick the moment kind of thing.
