SSRI anti-depressants (Paxil, Lexapro, Zoloft) are non-addictive, and they don't really alter the mind in the way alcohol, opiates and benzo's do. People taking an SSRI anti-depressent won't be impaired and they won't be in a euphoric state. If the dosage is right, they will just be relived of their depressive and anxiety symptoms.
