I was on adderall for about a year, however I weened myself off for awhile to try out life outside of the chemical. Lately, I've been considering switching back to see how it feels now that I have more prespective. I still have about forty pills from my last perscription but it expired about 7 months ago. Is this hazardous to my health or is it merely for potentcy? Any Useful and informed information would be great. Basically I don't want to have to buy a new perscription if it's possible. Thankyou for any help!
