True Holy Toast but its the same with PCP. Most PCP HCl decomposes to cyclohexenylbenzene and piperidine HCl, alongside tar and ash, when smoked, and theres a report on bluelight of someone smoking 3-MeO and getting the same effect, diminished effects, bad for lungs and ashes left over. 3-MeO is a tertiary amine so its not as basic as a PCE derivative would be, so the smoke isnt as harsh. Its recommended PCE like secondary amine derivatives are smoked as the HCl salt, but tertiary ones like PCP and 3-MeO to be smoked as freebase. Also, you cant get the salt conentrated enough for eCig liquid cause the crystals would plug up the vaporizing head, whereas the freebase is an oil which coulds in theory even be smoked pure, as a "one hit and your out" type thing.
