Dilated pupils are one sign that someone has used illegal drugs, such as: Cocaine, Amphetamines, LSD, Ecstasy (MDMA)

It is also a sign that someone is using LEGAL drugs such as an anti-nausea medication or over-the-counter decongestants.

Pupils tend to constrict due to the bright lights used for TV interviews. Stormy Daniels Pupils vs Her Lawyer's vs Anderson Cooper's. Interesting.
