How to code in new addictions?

Does anyone know how to code in new addictions? I’m trying to code in new drugs, and with them, their addictions. Slurm so deliciously addictive you could chew your arms off for a gulp.
And etcetera. But all that I can do is create an “Erroneous addiction” in game. I guess that’s what the game does when there’s no addiction in the addiction coding for that specific thing.

One more thing that needs JSONification.
