SWIM wouldn't recommend it simply because heavy petroleum based solvents take days or weeks to evaporate, thus an evaporation test to make sure it doesn't leave residue would not too great.
SWIM would recommend just making a brew of peruvian torch cactus, SWIM hasn't tried pure mescaline, but the effect and ease of the brew is so great he isn't even bothering with nasty extractions.
Also SWIM has been experimenting with cactus brew jello (original tek by phlux) and the gelatin makes it easier to get down, there is no need to chew, and seems to significantly reduce nausea
