Increasing Speed n Meth potency using acetic anhydride

[roidboy]

So anyways iv been thinking that since meth is just amphetamine with a lipophillic meth group added on which increases its brain permability,
and since heroin is just morphone heated with acetic anhydride to increase its brain permability aswell.
Would heating speed with acetic anhydride create an amphetamine with greater permability then meth due to the larger lipophillic sub group?
as Meth is only CH3 and Acetic Anhydride is significantly more lipophillic being C0CH3...
Im not too sure if anyone has done this, but if it would be possible to attach an acetic subgroup to speed instead of methyl im pretty sure, That if the molecule is still active it would be alot stronger since it would be entering the body alot more easily and redily.. making a stronger more potent amphetamine. think Speed, then think Meth then think Acetlyated Speed!! Have i hit on something here or not, does anyone know of anybody trying this?

thats just my too cents, what do you guys think??
