With all due respect, just because you haven't heard of them doesn't mean the definition isn't true. Next time, look it up.
With all due respect, maybe you should refer to actual discussions of debate rather than dictionaries. Ad hominem is virtually never used in this way in any of the historical documents from which it comes or in modern discussions of debate. And, as a technical term, it isn't really subject to the etymological fallacy either, so common public use (the kind most often documented in dictionaries), really shouldn't have much bearing on what you take as its meaning in the context of debate and logic.
Nor are dictionarities authoritative works. They're reference works, like encyclopedias. If something in an encyclopedia is demonstrably wrong, you don't trust the dictionary
over reality. In this case, ad hominem is virtually never used in the way you describe and very,
very never used that way within the discourse of academic debate where it sees the most common, most prototypical use. Moreover, dictionaries tend to be poor even as reference works with the average dictionary containing thousands of errors, extremely questionable value judgments, and technical definitions written by lexicographers with little training or understanding of the fields in question (sadly, this is sort of inescapable since lexical semantics is an ugly, ugly field even for experts and most lexicographers have little if any actual linguistic training).

Ad hominem is pretty much universally considered weak arguing, especially in lieu of actual information.
Ad hominem is
universally dependent upon the context. If the discussion of an interlocutor's character is relevant, the discussion is not fallacious. If the discussion of an interlocutor's character is irrelevant, the discussion is fallacious. That was my point - you can't just say "ad hominem!" and throw your hands in the air - you have to actually show that the use is fallacious. You do a much better job of that in this post and that's all I was trying to suggest that you do before.

Furthermore, even if I HADN'T partaken of any of those substances, I could still quite ably form a well-researched fact-based argument, so his assumption that I was bashing something I was morally against contributes nothing to the act of rebutting the argument.
We're talking about something for which many of the facts are personal and subjective. I would argue strongly that you actually
cannot offer a fact-based argument in the same way that someone with those personal experiences can. Though I will concede that you can offer an argument based on researched experiences of people who do have that personal knowledge, it would be folly to suggest that this isn't going to result in a somewhat weaker understanding of the issue under discussion compared to being one of those people. This is the difference between consulting an expert and consulting a consultant of an expert - you don't get quite the same kind of understanding.
In short, it doesn't absolutely disqualify you by any means, but it's certainly not unreasonable to suggest that a lack of experience with something so subjective might bias you in a particular direction.

I merely pointed out that marijuana is still considered a harmful substance, and that's stuff I can pull articles based on studies and investigations to support.
I can pull articles that state that evidence suggests that the world is flat, that the world is only a few hundred years old, or any number of crazy things. And every one of them will have real empirical evidence from experimentation in support of these conclusions. But that doesn't make them good evidence. There's a lot of bad science just as there's a lot of bad everything and one of the primary purposes of academia and the scientific method is to weed (no pun intended) that stuff out and base conclusions and subsequent research on what the scientific community agrees to be the most reliable data. Papers, even looking at them by sheer volume, will tend to lead you astray far mor often than looking at the consensus of the relevant scientific community. It's rare enough that there ever even
is a consensus on something that was previously controversial in a scientific community - scientists are notoriously skeptical and argumentative and the existence of any consensus (so long as it isn't the "uh, why do we all believe that again?" sort) is usually a very strong indicator, certainly stronger than the mere existence of papers arguing the opposite. For marijuana, the consensus is
overwhelming. You have to seriously dig to even find
anything stating the opposite view in the literature. Hell, even the questionably independent studies commissioned by the government
that effected and upholds the ban have universally reached the same conclusions

What difference does it make if parents would be consulted in this case or not? Yes, parents would be able to put forth a lot of emotional feedback as to why kids are worth it, but that's not an argument based in logic or facts, just their opinions. A man who doesn't want children would perhaps have additional motivation to research facts based on why kids aren't worth it, but that does not mean any facts he does come up with are automatically rendered unusable by his opinion on the matter. It may cause him not to fully research the issue on the opposing viewpoint, perhaps, but that's incidental, and the idea that all men who don't want children will poorly research the opposing viewpoint is a flimsy assumption. This further illustrates just how weak ad hominem arguments really are.
You're making the mistake here in assuming that the emotions of the people involved
are not relevant. Again, just like in ad hominem attacks, emotions aren't automatically irrelevant, they're just a direction where arguments commonly go astray because emotional appeals that are
not relevant come up so often in casual argument. When we're talking about whether it's "worth it" to have a child, emotional satisfaction is a
huge part of one side's argument and to suggest that it's irrational to consider it makes absolutely no sense - it is profoundly relevant. And you can research the emotional satisfaction of parents, but that's a very subjective quality that we really can't do a very good job of measuring (not to mention that once we measure it, we have to somehow quantify how much each unit of satisfaction is worth compared to the costs of childraising). As above, this doesn't disqualify someone from the discussion by any means, but a lack of personal experience in such cases is clearly a biasing factor since no matter how much research you do, you really can't hope to arrive at an understanding of the subjective feelings that rivals those who have actually been subjected to them.
