dxm-changing into powder?

[ace of spades]

is it possible to turn the syrup dxm(in robotussin) into a powder

 

[AbsGTR]

Is it possible? Yes. In your kitchen at home? Highly doubtful unless your kitchen is furnished by Fischer Scientific Inc. Besides, you can buy pure DXM powder (legally) if you search hard enough.

You can also buy pure DXM (no other ingredient) gelcaps-very easy to find
