No one has ever died of a marijuana overdose. Ahh, they favorite Pothead mantra of all time...
As a longtime Hazmat Officer I can tell you that too much of anything can kill you including water.
“A Virginia woman is facing murder and neglect charges following the death of her 4-year-old son, which authorities said was caused by consuming THC, the main active ingredient in marijuana.” The kid got into her stash of THC infused gummies and then died.

This is not to mention the thousands of people who have died after consuming illegal "marijuana" that was laced with fentanyl. Most of them had no idea it was anything but good pot...
According to your link,
“We know from really good survey data that Americans use cannabis products billions of times a year, collectively,” Humphreys told Fox5. “So, that means that if the risk of death was one in a million, we would have a couple thousand cannabis overdose deaths a year.”
In response to the reports of the Louisiana woman’s death, the executive director of the UCLA Cannabis Research Initiative told Insider “there is a theoretical THC limit that could lead to an overdose...but it’s basically impossible to consume a level that high.”
“[A] fatal dose of marijuana would require ingestion of fifteen hundred pounds in fifteen minutes — a physical impossibility for any human, even Snoop Dogg,” wrote David Schmader, author of a book about marijuana.
The dead baby you cite had THC in his system but was a victim of neglect.
As the article says, “If the child did indeed die of a THC overdose, it would be one of the first-ever recorded cases. Despite being used by nearly 50 million Americans at least once in 2019, there are no deaths recorded from the overdose of marijuana, according to the Drug Enforcement Agency’s website.
“The National Institute on Drug Abuse echoes this finding, saying there have been no recorded instances of death from marijuana alone.”
As for your other point, smoking fentanyl-laced marijuana is equally lethal as eating fentanyl-laced Rice Krispies. Therefore, we must ban breakfast cereal.
