Okay, but my argument was still on topic, and I was actually trying to discredit you in a direct manner -- something that is very much only a fallacy if it's not true. Look back at my point about Muslims and pork; would you really call it an ad hominem attack to say "well, as a Muslim, you're biased against eating pork?" So why would it be an ad-hominem attack to say that, as a teetotaller, you're unfairly biased against mind altering substances?
That comparison would be apt assuming I used any argument that doing drugs was an immoral thing to do, which is, in itself, ad hominem (another definition of it used is when someone tries to appeal to emotions or morality rather than logic during an argument). Instead, I was indicating that a harmful substance that does less harm to you than other available harmful substances is still a harmful substance and that the comparison itself should not be a reason to pursue the substance (as you had indicated in the post I quoted where you said there would be no reason why people shouldn't do Weed if it wasn't illegal).
EDIT: I should add that, as it stands, there is scientific data that backs up either of our arguments somewhere on the Internet, so you can't say that my position is pure bias anyway. A Muslim man can still put forth arguments that pork is bad for you WITHOUT invoking his religious views by pointing things out such as the fact that pork products contain a lot of fat and cholesterol. That would appeal to logic based on data rather than beliefs, which would be a legitimate argument.
First, appeals to emotion or morality are definitionally not ad homimen. They can be fallacious on their own, but they do not in any way fall into that particular category by any definition I've ever heard of.
Second, the notion of ad hominem is profoundly abused. Ad hominem is a fallacy in that arguing against a person
instead of the the topic at hand is illogical. If the character of the interlocutor bears on the discussion, it is
not illogical. I don't mean to suggest that that is or isn't the case here (I'll get to that in a minute), but it's worth bearing in mind. Generally speaking, it's a good idea to avoid ever saying "that's ad hominem, you're dumb!". Ad hominem is best thought of as an instructional tool for debate - a sort of warning flag that says "uh oh, this might not follow, better be careful". If someone is being illogical, say why, don't say "you're attacking my character and that's not allowed!", say "you're attacking my character, which has nothing to do with this argument". There are many, many arguments where an interlocutor's character has
a lot to do with the matter at hand, especially when morality, ethics, and legality are involved.
And I think this is a clear case where the comment in question bears quite a bit on the argument at hand. A large part of these debates naturally hinges on a sort of pros versus cons approach to evaluation of the substances. People who have never tried drugs are much more likely to pay attention to the negative qualities while forgetting why it is people do them in the first place. This would be akin to holding a debate on whether having kids is worth the trouble and not taking into account the reports of actual parents.
These things matter quite a bit when discussions get to the point where people are saying "they might not be that harful, but why do them in the first place?". In these cases, someone who hasn't done any drugs is at a significant disadvantage with respect to evaluating the positive aspects of the substances since they tend to be personal and largely subjective. Additionally, there is usually a strong value judgment involved in this viewpoint that things like pleasure are not an acceptable justification for risking one's health. This is an issue involving an interlocutor themself and is entirely relevant to the question and, as such, involving the character of said interlocutor is not fallacious.
Regarding scientific data and bias, all scientific data is not created equal. Studies are carried out with extremely mistaken methodology every hour of every day all over the world. Researchers blatantly influence their methodology to fish for specific results be it for funding, approval, reputation, or personal stake. A huge part of science is attempting to figure out who did a better job of testing these things, build a consensus of criticism, and move forward on the basis of that consensus. If we're discussing the potential harm of marijuana, the scientific consensus is
overwhelmingly in favour of little to no harm. We're talking the kind of overwhelming that makes such well-attested and agreed-upon phenoma as global warming look like a joke. Even organisations that are clearly biased against marijuana have come out with study after study after study suggesting that there is little to no harm and, in almost every single one, several potential benefits (beyond simple pleasure and experience, which require a pretty puritanical worldview to discount entirely themselves) that are at least worthy of additional study.
