I remember either John Lennon or Paul McCartney stated the Beatles NEVER played while high because "you'll sound like crap." They would write the initial passes of songs while high, then polish them up and play them later when straight again.
In other words, it was great for the initial ideas, but you can't be "professional" when high which is what a good song requires for polishing up.
As for the CA get together, I won't be going anywhere until my daughter is at least a couple of years old! She's not ready for travel and the wife won't accept me going off by myself while she has to stay home with her.
I've been around people who drink many times, I just don't like it when they get drunk.
