You can vape hash in a lot of rigs. Often, it's a matter of getting a screen and crumbling your hash.
No problem in the MFLB when I am at home. For when I am on the go, I use a variable volt mod. with a dry herb cartridge attatchment, works great.
The MFLB is really great - no doubt - but not really discreet enough for me
I have been using these dry herb cartridges from marijuana-ecig.com and they have been pretty good to me so far...:cheer:
