Note: The FAQ/on-topic has been updated to include the two points mentioned below.
Note: The tour has been updated accordingly.
TL;DR - We should add to our "off-topic" list in a way that does not ban questions about chemical principles. Note that my list includes personal medical questions, which are in the close question UI, but not the FAQ.
- Personal medical questions are off-topic. We can not safely answer questions for your specific situation and you should always consult a doctor for medical advice.
- Legal questions relating to chemical substances and techniques are off-topic. Laws can vary significantly by jurisdiction. You should consult a legal expert in your jurisdiction instead of a random person on the internet.
As long as it has a scientific background, asking about clarifications and / or mechanisms, I see no harm in allowing such questions.
I agree. I teach chemistry at a four-year institution and I deliberately try to address three important topics: very dangerous stuff, unethical stuff, and illegal stuff. Discussion of potentially illegal activities aimed at learning something about the situation is not illegal, unethical, or even inadvisable (else, how would anyone get through law school?). If I avoid these topics, I am doing a disservice to my students who one day may have to understand or work with these substances or scenarios as part of their job.
These kinds of questions can be thoughtfully answered in a way that helps the OP earn something while making it clear that they should probably not do what they asked about. Here's an example related to safety, which we think is generally on topic:
Hydrazine synthesis
Sometimes these questions come up innocently and what is needed is a rationally explained This is a bad idea
.
So, where does this lead us? I do not think we need much more in our FAQ to cover this situation. See my answer to this meta question:
How many shots will it take me to kill you with a neutron gun?
Questions that are clearly about underlying chemical principles are on topic. For example:
- Designing a theoretical synthesis of methamphetamine from phenylpropyne
Questions like the following are not on topic :
- Halp! I need mak my own codenie very fast what do I need to buy at the store... plz very important!
- Why is [seemingly innocuous substance X] a controlled substance in [jurisdiction X] but not in [other country Y]?
To be fair, questions like the first one about other compounds are also generally a low-quality or off-topic problem: I need 3-methoxybiphenyl tomorrow where can I buy it?
The second question is a legal question, which we should not answer. It is not about chemical principles, and laws vary by jurisdiction (sometimes significantly).
What should be in our FAQ?
I seem to remember something like the following in our FAQ a long time ago:
"Personal medical questions are off-topic on Chemistry.
We can not safely answer questions for your specific situation
and you should always consult a doctor for medical advice."
What I might be remembering is that statement from the close question UI, see Confused by Alternate Names.
Similar language about legal questions may be appropriate.
Biology.SE explicitly covers this issue in its FAQ:
Which questions are off-topic?
- personal medical questions and health advice
- philosophical or ethical questions related to biology
I am not advocating that we explicitly ban philosophical or perhaps even ethical questions (as that might suggest to some that we should not deal with safety!). Some of these questions that are off-topic can be handled by the suggestion that constructive subjective questions should not ask for opinions.
Adding the following to our off-topic list would be helpful in this case. I am including the language about personal medical advice, as it is a reason that we can close questions, but it is not explicitly stated in the FAQ (and it should be).
- Personal medical questions are off-topic. We can not safely answer questions for your specific situation and you should always consult a doctor for medical advice.
- Legal questions relating to chemical substances are off-topic. Laws can vary significantly by jurisdiction. You should consult a legal expert in your jurisdiction instead of a random person on the internet.
