And for my 2 cents - Adderal is dexamp succinate + HCL it is about 66% of pure dextroamphetimine or a relative dose of 66mg/day. That is still within the theraputic range.

I have been taking either 100mg ritilan or 50mg dexamp for 10 years for narcolepsy and am just STARTING to develop real tolerance )i.e. the theraputic value/benifit is decreasing.

But if you take amphetimines for the side effects they disappear quickly - so abusers increase the dose to stay wired.

After 1 year at 66mg their is probibly no wired or spacy side effects left - an abuser will go from 66mg to 200-300 mg/ a daY QUICKLY TO STAY WIRED.

In my opinion (based on 10 years of medical accellarant use) your friend does NOT have a problem.
