Yes, based on my experience Adderall reduces anxiety along with other ADHD symptoms. And when you stop taking Adderall, the symptoms, including anxiety, come back.
I wouldn’t call this withdrawal symptoms, though.
The following is not a recommendation, just an anecdote:
I used to self-medicate heavily with cigarettes. When I quit, all the ADHD symptoms hit me hard. So I got me some nicotine gum just to deal with that.
I’m currently on an extended vacation in a country where legally bringing my ADHD meds wouldn’t have been possible. So I bought a couple packs of nicotine gum and find they work well in managing my symptoms, until I get back home to my meds.
Probably wouldn’t do shit for anyone who was never addicted to nicotine, though.
