Open Question: I recently found Rohypnol (the date-rape drug) in my boyfriend’s jewelry box. Should I be alarmed?

I am sure my boyfriend does not require any kind of medical conditions sedatives. He occasionally will suffer from seizures, but his condition is working with the many years of drug control. I knew he was from the depression and anxiety may be the pain of the past, but his condition was not serious. I try not to jump to the worst conclusions, but I know I have to see. I should be shocked, or let it go?
