I get everyone is different and not trying to discount anyone's experiences. That said, I did take a class that taught me that one's reactions to and experiences with all substances, marijuana included, is related to one's "set and setting". In other words, there are variables that can change the experience each individual time you do it.
For me, sometimes I smoke weed and get very anxiety-ridden/paranoid, other times it's a very enjoyable experience. I can't really find a pattern or through line, except for maybe my built-up tolerance level or taking care of things to worry about beforehand, as sometimes each sort of experience happens regardless of where I am or who I'm with.
I recently started smoking much less, and partook with someone for the first time in months on Thanksgiving. He had a toddler staying in the house with us. And almost as soon as I smoked even a small amount, I began to trip hard on where I left my medication and if it was in place that the toddler could reach. Had he gone into my room when I wasn't there? Did he already find it and accidentally ingest it? Do I know where it is? I went upstairs to my room and searched my luggage for the pills (some were in a child-proof container, but I had others in just a plastic bag). Once I accounted for my pills, I put them all the way at the bottom of a zipped backpack. That seem to alleviate that concern.
While searching for my pills, I noticed the Air B&B had many roach traps under the beds. Then that became a thing to me that had to be immediately dealt with. I had to inform my friend that the roach traps were there, in case it was a threat of ingestion or contact to his son. My friend's wife was pregnant with their second child and ended up having a miscarriage that night in the Air B&B but I googled it and it likely had nothing to do with the insect traps.
But I was tripping.
Other times, I've smoked a bowl and gone to Costco or the farmer's market and been on cloud 9.
But it definitely can be a crapshoot as to what sort of time you are going to have.
