Edibles and inhalation are very different methods of cannabis consumption though. You're not even technically consuming the same compound, and that doesn't even take into effect the chemistry that happens inside of your body. While eating edibles is definitely healthier overall, the difference in effects and how your body processes each should definitely be taken into consideration
I don't know the last time I saw a cartridge that had vitamin e oil in it. Most cannabis products have moved away from using fillers. Usually the only additive, which is mainly used in distillate carts, are botanically derived terpenes. And BHO does not strip cannabis extracts of their aromatic compounds, that's blatantly false and doesn't even make sense scientifically. It's hard to take advice from a study like this that can't even get established facts correct.
Edit: Nice edit above. Still not very convincing when looking at today's cannabis market though
