Think this is ok, if SWIY gets rid of all the solvent. Good drying is necessary.
would use some solvent and water, so you've got two layers. The sugar and all the other crap go into the water phase, and the DXM
should wander in the solvent phase.
SWIM suggests SWIY to put the solvent phase on a big plate to speed up evaporation. No heating, especially not on an open flame.
Does SWIY know that there are also capsules and pills containing DXM?
