Connecticut has a licensed adult-use market, so the practical effect is a channel switch rather than a loss. The hemp shops selling delta-8 and THCA lose their inventory, and the licensed dispensaries that were already open continue exactly as before.

The 2018 Farm Bill defined hemp as cannabis containing no more than 0.3% delta-9 THC by dry weight. That measured one molecule. The new definition measures total THC, which folds in THCA and other THC isomers. A plant that passed the old test by holding its THC in acid form does not pass the new one.
This is the provision that does most of the work, and the one fewest people know about. It is not a percentage, it is an absolute quantity per finished package. A 5 milligram gummy fails. A can of THC seltzer fails. A full-spectrum CBD tincture that nobody would call intoxicating can fail as well, simply because a whole bottle adds up.
Anything falling outside the revised definition stops being hemp in the eyes of federal law and is treated as a controlled substance. Industry attorneys have estimated that roughly 95% of the hemp cannabinoid products on shelves today sit outside the new line.
