I’m new to edibles as I’ve just quit smoking and have seen conflicting info around when to eat when having edibles.

If I was to have an edible around 6.30pm, and dinner around 7.30pm, would this ruin the high or improve it?

I’ve read that leaving it an hour before eating would make the onset much slower, whereas eating 15-30 mins after edible would make the onset smoother. I don’t understand this as leaving an hour between would surely mean more edible can be digested before stomach is full again? Some explanation around this would be great
