 No person shall manufacture, possess, have under his control, sell, prescribe, dispense, compound, process, deliver or administer to another person any restricted substance, except as authorized in this chapter and section
10-212a
, except that no vendor of the volatile substances enumerated in subdivision (49) of section

 shall be deemed to have violated the provisions of this chapter insofar as sale, dispensing or delivering of one or more of said volatile substances or compounds containing said chemical substances is concerned, unless he knew or should have known of the improper purpose to which such substance was to be put. Insofar as substances containing said substances are possessed, sold, dispensed, compounded or delivered for licit purposes, i.e., other than to produce a stimulant, depressant or hallucinogenic effect upon the higher functions of the central nervous system by breathing, inhaling, sniffing or drinking, such substances are expressly not restricted and neither the regulatory provisions, including but not limited to record keeping, licensing and the writing of prescriptions nor the criminal sanctions and proscriptions of this chapter shall apply.

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
