I know many people who were more angry with stimulants, especially Vyvanse (According to my wife, I definitely had that side-effect).

However, one symptom of ADHD is something my therapist refers to as "explosiveness" which is a very sudden change from not angry to extremely angry and then often right back to not angry. Note that this can also be a symptom of bipolar, and misdiagnosis between the two is why they tend to screen for bipolar before prescribing ADHD meds.

This is not what I experienced on Vyvanse; rather my baseline level of "being annoyed at things" was much higher, so it was easier to make me angry.
