What are the side effects of Adderall?

it can be. but generally in higher doses

It’s different for everyone and can depend on whether it’s extended or instant release. It also depends on whether it’s the brand or the generic - and what manufacturer made the generic since they differ slightly (different fillers, etc.). Personally, I’ve experienced dry mouth and increased heart rate the most. Occasionally, I’ve had trouble sleeping (usually after taken a break and starting again, and/or if I took it too late in the day). I’ve also experienced appetite suppression (and it use to make my appetite for particular foods finicky), but not so much anymore.

Adderall belongs to the drug class of CNS stimulants, it is a controlled substance, schedule 2. It is potentially highly addictive.
