I’ve heard some either Australian or British or both that pronounce H as something close to Hayche. Using a similar accent, and making it a bit hard to hear by mumbling or something, Hayche and age can sound similar.
Hayche is of course made up, but that’s how it feels to me to write it, but I’m no linguist, and I don’t know how to write in pronunciation guides.
I don’t vape or smoke (I have used a few THC carts from time to time, but I usually just take half an edible, and the cart is used maybe once a month if that often), but I still will criticize broad generalizations from limited studies, especially not peer reviewed.
I do agree that their findings seem to be more about regulation than vaping itself, and I’m happy I don’t vape, but I’m not going to act like I can just confidently tell every person I know the science has proven their habit is worse than smoking.
