Why is there a difference in potency between pure cannabis oil, or your flavored THC eLiquid?

The 2 products are designed for different uses, one is for stealthy medicating and the other is not. The Difference in potency comes from the fact that it must be thinned 4:1 with PG/VG in order to make the solution function correctly in standard clearomizer tanks and replenish the wick before it dries and produces a “dry burn” taste for the user.
