All, First post, so please be gentle..... I am about to start mixing my own CBD vape juice in the near future, but before I do, I want to try to understand the commercial offerings a little better. The key question, is are these specified in the same way across brands - and is there a legal requirement? So for example, I see vape juice in shops marked as "100", "500", "1000" etc....but bottle sizes are different and prices range incredibly, so it leads me to believe that there is inconsistency. My understanding is that these specifications "should" be in mg per 10ml of juice. Is that correct? If so, then a 10ml bottle of "1000" CBD oil should contain 1g of pure CBD or have 10% CBD content. So is this really the case - or is there latitude - or just no regulation? i.e. an unscrupulous vendor could sell a "1000" grade juice, but specify is at 1000mg per 50ml of juice - yielding a 2% juice in reality. Anyway, that's what I kind of want to understand! As to my plans for creating CBD juice I am going to use CBD Isolate in a 50/50 PG/VG base. Not sure about flavour yet, but we will see where we go!
