> Also, in British English "Chemist" means "Pharmacist". I always wondered, what they called a Chemist?

(Brit here). A shop that sells pharma products is often colloquially called 'a chemists' but the people who work there are typically referred to as pharmacists. 'Chemistry' as studied at school and Uni is totally about chemicals in general and not drugs (which would be pharmacology). Someone who described themselves as a chemistry student or professor would almost inevitably be perceived as someone who is working with chemicals.
