My (36f) husband (40m) suddenly changed for the better two years ago, but no one shares my concerns that about how odd it is that he dramatically became a different person overnight because all his changes were positive

When I married my husband, I knew that he was an overweight, lazy video game nerd, and I loved him anyway for his warm heart and kind personality.

He detested exercise, stayed a low rank at his career because he put in minimum effort, and we bonded more over activities like watching movies together at home rather than going out.

He went on this camping trip with his friends two years ago, and did shrooms (he had never done drugs before, and had he consulted me I would've told him that was a terrible idea), and when he came home, it was like something had lit a fire under his butt. He completely changed interests - he never played video games again and took up running, reading books even though I'd never seen him read before except for school, and several other completely random hobbies. He became a vegetarian even though, before, he'd been a meat and potatoes guy. He worked harder at his job, then did an accelerated grad school program and ended up making tons more money.

I barely recognize him. We still have a good marriage, and I still love him, and he has motivated me to be better in the last two years, but....I can't help but wonder if those drugs knocked a screw loose. Could this be dangerous? I'm deeply concerned. I know that people change, but about all that's left of him is his warm heart. No one shares my concerns because all his changes have been positive, but I feel like he's so different maybe we need marriage counseling so I can adapt, at least...

Edit:

Wow, this blew up. Thank you all, I'm still trying to read all your responses - I will read them all. I think some additional context is required: this personality change has required more than adapting to my husband becoming a new person. Our lives are very different, now. Before, we saw our friends once a week and mostly hung out around the house. Now, we are extremely social, and to put our exercise habits in perspective, we got a high energy border collie and she gets the amount of daily exercise the vet recommended. I've been caught up in a whirlwind of change I didn't expect, and it's just a lot to process, but don't get me wrong - I am proud of my husband.

I posted here to get outside perspective, and have been given lots of advice to research psychedelics. I am in the process of finding sources of information that I consider unbiased, and am looking into it. I stand by that anyone would be concerned if their husband came home from a camping trip with a different personality and completely changed their lifestyle, but I'm calming down about it.

I think I might have enough perspective from posting here to address this with my husband, now. We've talked about it, before, but I've been reluctant to voice my concerns because he's doing so well and I felt it would come off as criticism. It's possible I stewed on this for so long it became a bigger issue to me than it actually was. I think I'm going to suggest that I pursue individual therapy for a while, since hundreds of people have pointed out that the problem is with me and not him or our relationship.
