Today I learned on the Internet that Tylenol is more dangerous than meth, cocaine, or fentanyl.

Wait, no I didn't. That's absurd. Tylenol can cause long term health issues if used in excess (or death, for extreme overdoses), but most illegal drugs are illegal because they can cause immediate death even at normal usage amounts.

Meth used to be available over the counter in pharmacies in the US.

No drug I'm aware of causes immediate death in normal usage, except perhaps those used for lethal injection. Would you like to elaborate on that? Tylenol, on the other hand, causes an unpreventable (no antidote) slow drawn out death over about a week, where your body will be slowly decaying and you have time to say goodbye to all your loved ones, if you take a few times the normal dose by mistake

You would have had a better point if you didn't include cocaine which is only really dangerous for people with severe heart problems or by using it in combination with depressive drugs that it temporarily suppresses.

If cocaine was really a problem then C-suites and politicians would be regularly dieing.
