This idea might be a prudent one - and it might not. As others pointed out, this doesn’t prevent consumption, but makes it slower to consume. If a child is able to defeat a child safety cap, is the reduced flow really going to prevent more ODs? How many ODs are from actual children self medicating, and how many are from parents accidentally giving too much medicine? If the number of ODs have recently increased, what is the reason for that? We have had the same child lock system for years. Would education as to the dangers of children’s medicine have more of an impact? One thing I’ve learned in my limited run on this earth is the solutions to problems are not always what “common sense” would dictate. Not every act made for the interest of the public’s safety is a rational, prudent one.
