after a very long time trying traditional e cig bases to thin bho for vaping in an e cig,, finally i found a forum on the topic of a product called " Rite Stuff " on E bay they sell it in 5 ml bottles , its real easy all you do is put 1 gram bho (honey oil, shattered) in a shot glass melt it on a coffee mug warmer add Rite Stuff, let it heat for a couple minutes mix it well suck it back into bottle and put in any e cig Rite Stuff is A PEG USP Solution(no Nicotine and no flavor) which dissolves shatter and at that ratio is perfect for any e cig and it taste great once mixed,,,I hope this helps everyone,,,i love it and it does not seperate like PPG and alot of PEG liquid of the wrong molecular weight
