It depends on what exactly you envision the point of using these devices for dmt is. If all your looking for is low dose effects with the need to replace the $5 coil every few trips, with loss of product everytime you transfer the juice into another tank like you have, inconsistent dmt/pg vaping ratio, and the probability of leakage happening then sure using a tank is great.

Regardless, a dripping atty will work just as good for sure without the issues a tank has with dmt. This i already have experienced if you just read back several pages on this thread. A rebuildable will only work better, this is for sure known.
