The main purpose of this legislation is to change the rules around how long authorities have to bring charges for certain drug-related offenses that lead to death or serious injury. It aims to ensure that law enforcement can take action without time limits in cases where someone suffers severe consequences from the misuse of controlled substances. The key provision of this law extends the time frame for prosecuting specific drug offenses. Under the existing law, there are time limits for filing charges, known as statutes of limitations.
