I think that concentrate manufacturing should be something we regulate like cars. You can do damage to yourself and those around you making oils if you are not careful, just like when driving.
Still, why do we need to ban across the board and stop patients access? Couldn't we just have a testing/licensing regime to ensure that those who use solvents only do so in a safe way?
I do agree however that solvents that are both flammable and stored under pressure need to be regulated more strictly, but even here surely we can make sure that processors know their shit safety-wise and then can be given a very cheap or free license (it is crucial that cost does not prevent patients from making their own medicine safely!).
This kind of blanket banning of kinds of extraction is just more prohibition. Why don't we take the opportunity for some real public safety regulation, harm minimization and education instead?
Prohibitions on concentrates are especially strange since to me, it makes more sense especially for medical users to be using concentrates than flowers. Anyone who has stuck some bud, hash and then shatter all from the same source material into the same vape (I used a Mighty for this experiment) can tell you that they get better effects from the concentrates and far less respiratory irritation!
Still, I think it would be good to sieze the opportunity to regulate and especially educate but not to prohibit (either by de jure or de facto routes), I see so much oil posted around FC these days which I would not touch with a ten-foot dabber! lol
