I'm all for Alcohol being less available, Paracetamol isn't my cup of tea either and discourage its use, a search for Nutmeg has brought nothing that seems to be supportive of it being overly dangerous, and a quick google for dextromethorphan also seeems to be inconclusive (wikipedia cites adverse effects in doses up to 75 the usual dose, so unless one can buy it in extra large capsules I don't think it is relevant).

I have a hard time believing that you were serious about the latter two examples, given what I found.

Well there is your problem. You don't actually know anything about the subject and a "quick google" is a poor substitute for actual knowledge.

Nutmeg is a psychoactive substance at the right dose and at around 7-8 times that dose it can be lethal. That is more dangerous than alcohol.

With dextromethorphan the ratio of a dose that gets you high to the dose that kills you is about the same as alcohol.

How many people have died of a nutmeg overdose? http://www.ncbi.nlm.nih.gov/pubmed/11343860 seems to suggest that it's rare.

Fair enough, but that is a very different measure of "worst".

Death from cough syrup overdose is well known and cautioned against in the drug taking community.

Why? When taken at the correct dose it's a safe, effective, pain killer. People do need to be careful to avoid overdose, which means that packets should probably be a bit clearer when they include paracetamol / acetaminophen.
