So really, not sure what answer you were looking for here. If its a vape with weed, you will likely get high. If it's nicotine, you might get nicotine effects and so on.

 
You're just vaporizing things instead of combusting.  

Now, have I hit the vape with a kgirl? Yes. Was it anything special? No... ie if a cig tickles your fancy, ecig is similar. Etc.
