welcome to Healthcare Magic.
As you have history of addiction then stimulant like amphetamine
is not good option for treatment of ADHD in your case. In your case there is need to confirm ADHD diagnosis in your case.
In your case inattention may be due to:
-Addiction and substance withdrawal also associated with inattention and cognitive deficits.
-Substance induced anxiety
Non addictive drug which help in ADHD: Atomoxetine
Wish you all the best.
