Hollywood Goes Up in E Smoke? Does E Smoking Make A Difference in Movie Mood Making?

The above movie clip is from The Tourist, and features Johnny Depp smoking an e cigarette on a train. 
Hollywood movie makers use smoking heavily in movies since the first images were burned onto celluloid.  The vision of a man or woman lighting and smoking a cigarette is used to create a mood, pause a scene or help to tell us something about the character.  Does that change when the character is smoking an e cigarette?  Compare with the below movie scene classic.
