Several new laws have gone into effect for the start of the new year.

The state's clean slate law will now erase convictions for possession of small quantities of marijuana. The law will also erase other low-level misdemeanor and felony convictions. State officials say it could take six to eight months for some cases to be processed.

The state's bottle return program will also expand to include iced tea, coffee, sports drinks, plant water and other beverages that were never charged a deposit in the past.

In 2024, the deposit will increase from 5 to 10 cents.

The state's truck highway use tax is also going into effect. It requires all commercial truckers to register with the state and pay a per-mile use fee.

Many state lawmakers are getting a raise today. Gov. Ned Lamont's salary jumps from $150,000 to $225,000. Legislators salaries will go from $28,000 to $40,000.

This is the first pay increase for many elected positions in about two decades.
