What the record says

Connecticut sets its schedules by Department of Consumer Protection regulation under Conn. Gen. Stat. 21a-243. Schedule I in Regs. 21a-243-7(c) names psilocybin, psilocyn, dimethyltryptamine, diethyltryptamine and 5-methoxy-N,N-diisopropyltryptamine but not 4-AcO-DMT, and has no structural tryptamine class. Chapter 420b contains no controlled substance analog or designer drug provision, and 21a-243(h) adds only substances scheduled federally, which 4-AcO-DMT is not. A product that also contains psilocyn is reached by the psilocyn entry. See the federal page.

(23) “Hallucinogenic substances” are psychodysleptic substances, other than cannabis-type substances, which assert a confusional or disorganizing effect upon mental processes or behavior and mimic acute psychotic disturbances. Exemplary of such drugs are mescaline, peyote, psilocyn and d-lysergic acid diethylamide, which are controlled substances under this chapter unless modified.

Regulation - Page 6 of 7 Connecticut eRegulations System ,  Tracking Number PR2025-018 ,  Posted 9/18/2025 Statement of Purpose The purpose of this regulation is to designate new substances to the controlled substance list as required by Public Act 25-101, Section 4. This new law requires the Commissioner of Consumer Protection to designate the substances added to subsection (i) of that section as controlled substances and classify each such substance in the appropriate schedule. Since such substances currently have no medical use, pursuant to the Federal Drug Administration (FDA), and may not be prescribed or dispensed by a medical professional, the Department of Consumer Protection proposes this regulation to place the substances in schedule 1. However, if any of the substances are rescheduled by the FDA, this regulation contains an existing provision in subsection (g) to adopt the schedule determined by the FDA. Regulation - Page 7 of 7
