I'm also type 2,and kept a very close eye on my sugars during the month of August, and say no impact on my blood glucose levels. I was testing 5 times a day for the entire month, and kept track of everything via a spreadsheet.
I'm also a chain vaper, so if it did affect things, I probably would have seen some elevated levels.
At my next doctors appointment, I'm actually going to give the doc a copy of the spreadsheet, so he can see it.
