The patch stops working much faster while ecig's effect never seems to wear off.

I can only assume that it is because the patch maintains a constant level of nicotine in your bloodstream causing tolerance to develop faster and it is unable to spike the nicotine concentration unlike ecig when you can take a deep drag.

Ecig gives a totally different feeling than patch. You'll definitely feel it hit when you take a long deep drag.
