Ketamine certainly is addictive. I reckon the recreational value of K is seriously weakened by this factor. There are better things to trip on, that don't risk compulsive over consumption.
Tolerance builds quickly and a strong mental addiction develops quickly. Having to take a shit ton constantly means you're pissing brown within a few months and cessation means withdrawals (nothing even close to heroin, but still there).
That it does, but you cannot dismiss the addictive qualities of ketamine with such a statement, because it is an addictive drug. What part of tolerance build up and withdrawals makes you think it isn't physically addictive? Both are physical documented phenomena.
