Well, I grinded 8 high quality seeds (I've tripped on 4-5 of these before) to a pretty fine dust and applied it between my upper and lower gums and my lips. Before this, I had brushed my teeth and cheeks very well, and keeped Listerine for a long while unitl my gums hurt, etc. While keeping the seeds between my gums and lips some of them ended up below my tongue, where I kept them.
After about 25-30 minutes, I spit out the seeds and started waiting. About an hour later I was feeling no effects, so I went and had dinner. No nausea or anything.
So now 3 hours and a half have passed, and I have felt no effects from the seeds, no pupil dilation, etc. I find it very unlikely that anything will happen in the next hours, given that when I swallow the seeds by hour 3+ I definitely have dilated pupils and more. From what I've read, the onset of mouth absorption would be, if anything, quicker than swallowing.
So what could have gone wrong this time? (For the record, I have been taking piracetam, choline, and vinpocetine for several days, and from what I've read piracetam especially can in fact potentiate certain drugs such as lsd and ecstasy.)
