I find myself to become more empathetic on low doses of dopaminergic stimulants. However, at high doses, I feel more egotistical. A nice 20mg of Adderall IR or 30mg of Ritalin will allow me to really talk to people and listen to them deeply. I actually learned how to do this on stimulants and now rarely take them recreationally, but I still kept my empathy-skills.
