I'm not sure I'd use the phrase 'trigger happy' for doctors willing to prescribe stimulant medication to adults. The literature is clear that the stimulant meds are very effective for ADHD and the side effects of normal doses are pretty minimal. https://slatestarcodex.com/2017/12/28/adderall-risks-much-mo... is a pretty balanced take on the risks/benefits.

So, as a doctor, if an otherwise responsible adult is stating that their inability to focus is having a negative impact on their life, and you know there are reasonably safe and potentially very effective drugs that can be tried, what, exactly should hold you back? Likewise, as an informed patient, what is the harm in trying a low dose and seeing if it helps enough to be worth it?
