I've been wondering if anyone else has had problems with a reduced short term memory from the use of ayahuasca?

I suffer one for sure, but it might be other things than the ayahuasca, like I used quite some weed years ago, and now occasionaly, but it might still effect my memory stronger than others because of this more intensive use in the past. Last week a drank some aya with someone, for whom it was the second time, and he reported a worse memory afterwards while he never smokes weed. Maybe coincidence or a specific biochemical makeup, or maybe not...

So, just wondering; anyone else here experiencing this?
