In the UK, they can encourage you to take certain kinds of medication. I've seen them get quite pushy with this. They can't force you unless you get committed.
It would be nice if you pointed out your edits on your comments as you made them, and kept the original message up - you're making large claims (including that psychology is being used present day to justify racism), but you're really ruining any ability to have a dialogue if you continually edit and adjust your statements.
Psychologists can never force someone to take medication, even if that person is detained under the act. ("Sectioned". We don't use committed over here.
