What is the simple reason for this and do you think this is why my doctor loves to prescribe adderall but refuses me dex which I absolutely prefer. Is it as simple as the Levo salt has an NE affinity more so?
Well there's a few reasons. The levo isomer does have more NE affinity, but for both amphetamine and methamphetamine, the dextro and levo isomers have different affinities for 5-HT, NE, and DA. I could try to dig up the chart if you're interested in looking at it. It also compares other stimulants like MDMA and MDA.
Also, some people with ADD/ADHD need the 25% of the levo isomer in Adderall because they need the extra "push" it has. However, for other people, they are prone to anxiety/irritability/depression, and for them, just the d-isomer (like dexedrine or vyvanse) may be a better choice.
Additionally, Dexedrine is more potent MG for MG than Adderall is from what I know. The specific salts in Adderall do not equal up to the same number in an equivalent amount of amphetamine base.
