There are two types of ketamine i have seen, one in a liquid vial that you dry up and scrape the remains and the crystal kind that looks like sea salt that you crush up into a fine powder and sort.Yes ketamine does fuck you up. i know somebody who accidentally drank liquid k and he got chemical burns in his throat. I also know someone who has been doing ketamine on and off since the late 90's. He has serious ulcers in his stomach and damage to his esophagus from ketamine running down his throat. This would lead me to believe that ketamine is very corrosive. You can't buy it anywhere except for other countries like mexico/south america. Your probably going to have to deal with some street dealer or meet someone selling it at a rave.
