Old tobacco playbook gets new use by e-cigarettes

73. I will explain that smell

These e-cigs (not the disposable type, but the refillable type) come with a replaceable wick.

The electrical current from the battery creates heat, through impedance within the wick, to vaporize liquid that is "wicked" from the fluid chamber. These wicks have a life span. That life span is determined by burn "damage" to the wick from repeated use, but more often from not being moist when current is discharged through it. Once that "burnt" taste is evident, it becomes increasingly nasty to the palate, as well as leaving a slightly burnt odor. An expired wick will leave that smoke odor.

I immediately replace the wick when that burnt taste is evident. Use an expired wick long enough, and it will "contaminate" the fluid within the chamber so that even when replacing the wick, the burn contaminated fluid will retain the same taste and smell properties.
