Just weed. Interesting how you chose to go along with the idea of being a demon, since a demon with strange power limitations might also be able to dodge a question, yet unable to lie about its age. You know what's scarier than demons though? Humans, which both of us are - the species that came up with the idea of injecting someone with drugs against their will and accusing them of being psychotic, so their only choices are to either try to prove they're not psychotic while continuing to be injected against their will on the basis that the injections are the reason for the lack of psychosis, or begin acting increasingly psychotic to weaken that narrative but still continue being injected against their will on the basis that supposedly this will somehow reverse the course. If you can successfully make such a fate happen to me, I can only hope demons and religious shit like that are real so they'll deal with you later.
