well went to herbal solutions in Ann Arbor and got the joyetech electronic joint (ecig battery) and got a couple cartridges. Works well and very stealth. It may not be the strongest meds but will do what I need it to do till I make my own cartridges. So far I am very pleased as I can hit this thing anywhere and no one would have a clue of what I was doing. So all in all good so far and I will let you all know how it works out with my project. Now all I have to do is eventually figure out how to fill my own cartridges and will be good to go but as I said for my project the cartridges I bought will do the job for now.
