My initial reaction is no way. I don't see how there could be enough of anything besides PG and alkaloids in there to have an effect.

The mouth plastic bits are probably polycarbonate: Polycarbonate - Wikipedia

Wikipedia says it has poor resistance to acids and good-poor resistance to alkalis, so that seems to leave the door open for a basic solution to do some damage. It also says it has good-fair resistance to oils and oils are nonpolar, so I'm not sure benzyme's assertion is correct, but perhaps he could elaborate.

Regardless, I don't know of anyone that has put as highly concentrated of solutions in plastic cartomizers besides us, so we're 2 for 2 with concentrated solutions of PG/DMT cracking them. I think it makes sense to just go with glass. Even before all this it weirded me out they'd make them out of plastic in the first place with all the heat and chemicals in them. The glass ones really don't cost that much more.

Anyways, I'm all set to start back down this path myself on Tuesday, so we'll see how it goes.
