did you visit ko phayam after pandemic? it is totally changed now. i don't recommend to go there anymore. the island is full of german all-inclusive sheeps and it's all about money business. also locals barely smile or talk to you. drunken people are driving fast with scooters.
i visited there in 2017-2018 and got that seedy brick you mentioned about. this is embrassing to say but it was probably the best high i've ever experienced in my life. most euphoric and positive happy smiley high that lasted for 4 hours. a couple of puffs were enough. since then i've been trying to find something similar strain but it seems impossible mission. also the smoke of it was super clean to inhale and exhale and it burned so smoothly. so good memories of that stuff. i was thinking if it was laced with something. can't be sure. consume too much and you might get hysterical laugh - or paranoia.
ko chang next to phayam was chilled place but i'm not sure if i wanted to visit there again. maybe it was too small and quiet for my senses. less activity but perfect for escaping city chaos.
now i'm trying to find a place that is like mix of phayam and chang. do you know any? (can be outside of thailand but in se-asia)
That's too bad to hear, I was there in 2016 and it was amazing. It felt like any normal small island aside from the shops near the port and a few bars/resorts here and there. A good Italian restaurant ran by an Italian woman and her husband iirc. Oh well, onward and upward I suppose.
I've heard Ko Rong in Cambodia is still laid back, but I haven't been there.
