Chemical Fascination Binges lean towards Harder Drugs?

[MikeLemmer]

I have a colony with 3 colonists with Chemical Fascination and a variety of drugs (joints, beer, psychite products). When the Chemical Fascination colonists binge, 95% of the time they binge on psychite and not the beer or joints. Is this working as intended?

Yes, I believe it does work as intended; Chemical Fascinated prefer hard drugs, Chemical Interested will prefer simpler drugs.
