I've had my Smoke Stik over a week and after refilling my Smoke Stik and AzSmokefree cartos several times, I boiled them. They just don't seem to be working that great anymore. I blew out all the water and dried them for 24 hours then refilled. The draw is really tight and I'm not getting much of a throat hit it seems. Are the cartos just dying or did boiling do that to them?
