I don't think hes talking about making naphtha hcl lol. I think he means salting the freebase alkaloids out of naphtha with hcl water. If its for dmt, don't even try, the hcl will NOT dry as it sucks water right out of the air. Mescaline is not soluble in naphtha, so if thats what you were trying to do then that won't work either. Fumaric acid water, vinegar, or another acid besides hcl could be used to salt dmt alkaloids out of naphtha though.
