Wellbutrin works as an reuptake inhibitor for dopamine and norephedrine, that's why it's an anti depressents and also commonly used to treat ADHD.
There's other drugs that work as reuptake inhibitors for Dopamine and Norephedrine.
Like cocaine and Metylphendiate (A famous ADHD medication)
The difference is that Wellbutrin is XR and slowly releases into your body over the day, and your body gets used to it while remaining a low tolerance so it works as an anti-depressents and not recreational drug.
So I thought, if you were to snort it, it would instead get absorbed into your blood stream directly and therefore release it all at once which in theory should act as an recreational drug similair to cocaine or Methylphendiate. So I googled it and I was right.
