IMO what really matters is the THC concentration. I've suffered from generalized anxiety since early childhood, and the one time I tried typical, high-THC content recreational cannabis things didn't go well. I got a full-blown panic attack, and maybe even psychotic symptoms for a while, afterwards I wasn't sure whether I imagined some things or not. Later when I tried a CBD product I didn't have any problems, just a slight calming effect comparable to having a couple of beers.

Since then I've also found out that I probably have increased genetic likelihood of developing schizophrenia. I'll never touch anything with significant THC concentration again, just way too risky.

I feel that propanolol helps with physical effects of anxiety (which are not much of a problem for me), but doesn't affect the mental side of anxiety the same way benzos do. It's much less addictive than benzos of course, and preferable for that reason if it works.

I only get the physical effects, which is why it works so well for me.

Having fewer children globally would make the world a better place. Less people with better quality of life is better than more with much worse quality of life.
