We’re missing a key component of the discussion: dose. Therapeutic doses and recreational doses are vastly different things. A drug that’s addictive at recreational doses isn’t necessarily an issue at therapeutic doses.

Therapeutic Adderall doses typically start at 5mg whereas recreational users may be using 30-60mg or more. That’s an order of magnitude difference! Now, a long term patient taking prescription Adderall may eventually have their dose up to 40mg but they will have developed significant tolerance to the drug so that it doesn’t affect them nearly as strongly as a recreational user would experience popping 40mg out of the blue at some club.
