Maybe if you take 1g regularly but if you’re doing it a few times a month in small doses that is highly unlikely
I mean, that kind of begets the problem. Addiction wouldn't exist if people could control their drug use in the first place. I'm sure plenty of addictions started with "I'll only do this once" or "this is just a weekend thing".
I don’t think ketamine is considered to be addictive...not to say you can’t overdo it if you like the feeling.
