I definitely notice the oral absorption with edibles with just normal eating (not sure if everyone gets that? I have a pretty low tolerance), I've never thought to keep it in my mouth on purpose though. I'll be testing that out next time I have some.

I was planning to go on a trip later today so I'll be trying that trick with shrooms, thanks for the tip.

Edit - I'm mostly back to earth now; I really liked it. normally I feel kinda weird and tingly for the ~hour it takes for shrooms to kick in and sometimes that can put me in a bad headspace, but there was a nice and very noticeable immediate effect with chewing them for ages that helped me get into the right mood to appreciate the 'main event' more. I really needed it :)
