Kidney failure from oxalate crystals makes the buzz permanent. There are stupid people all over the world, who think a short buzz is worth ingestion of poison. Darwin at it’s finest. That these particular poor souls are Russian makes the news.
Alcoholism overrides the brain. I once heard a Nobel chemist say he was watching folks in a third-world country swig on something and laugh and have fun. He asked a lady what it was they were drinking and she told him it was denatured alcohol which would make you blind. he said, being a chemist, he knew exactly how the alcohol went through the system, and finally ended up doing irreparable damage to the optic nerve - and concluded with, "But I was thirsty!"
Perfect example of what alcoholism does to one's thought process.
