Ok maybe its just me but my first thought was about cosmetic changes.. is it illegal to make your girlfriend hotter? (with her permission/without?)  larger brests? smoother skin...removing scars.. whatever else but the modifications would be small to negligent in this as you are not actually changing it from what it is.. And what about changing yourself.. make yourself a little stronger.. faster.. Not inhumanly so.. but some people who dont normally work out much would probly not mind being even just in good shape. Now granted it would probly be better to use a temperary potion for the self improvments as anything other than temperary might be a slippery path down to dark magic ending with tenticals comming out of your head so you can hold your coffee as you type.
