Everyone is different, and it's unfortunate that your friend's experience is not good, and that you don't know anyone with a healthy relationship with their medication.

The truth is that lots of people manage their stimulants just fine. Across everyone I know on stimulants, 8 friends and family, none are as you describe. These are people I physically see on a regular basis. No one is addicted, high, unable to function or experiencing material personality changes. Every single one of them is taking low to moderate doses, as needed, and says their stimulants changed their life for the better, allowing them to function "normally" at work or school.
