I just got a new Evape pen - Fantastic IMO! I swear, it is so discreet and odorless, - bet you could smoke it / take a hit - in Church, and it would not be noticed! 
Now I have been thinking, always a dangerous activity - and I'll bet there is a way to home brew the tinture or concentrate and refill the commercially produced cartridges?
Wouldn't be cool if everyone could make the evape recyclable for their own personal use?
Note - if you get one, professional advise is that if you exhale visible smoke, you took too big of a hit.
I am new to it - one or two seconds is more than enough.
