Language for signs?

We had instruction from Fitwel; they seem more focused on the language specifically addressing tobacco, despite what their manual says:
"There are two main things to watch out for when providing the signs: 

1. If you are providing new signage: make sure that the sign says the use of tobacco products is prohibited. This can be as simple as saying "No Smoking or Tobacco Use" without the use of any icons. 
2. If the sign is existing and includes a mention of smoking or has the icon of a crossed out cigarette: you need to provide additional text similar to the above to clearly indicate that this includes tobacco use and not just smoking."

I ended up emailing LEED Coach a little while after my post with a proposed approach. We came up with a succinct-as-we-could-make-it statement that we thought captured all possible substances:

"In previous projects, we were able to simplify the sign to read 'No smoking within 25 feet of building'.
Please confirm if "All tobacco use and smoking prohibited within 25 feet of building" is sufficient to meet the requirements, or if you have other concise, suggested phrasing."

Their response:
"'All tobacco use and smoking prohibited within 25 feet of building' would be acceptable. It would be acceptable to continue to use the same language that you've used previously for the signage. The LEED v4.1 BD+C Guide includes the following guidance on page 206: "Tips for good signage include drawings, photos or signage with language communicating clearly interior and exterior no smoking policy, or explicit language such as ‘no smoking allowed within xx feet’ and ‘smoking is allowed in designated smoking areas only’ and indicate on signage what those areas are etc."   ​

So, "All tobacco use and smoking prohibited within 25 feet of building" seems to capture the requirements of both. That's what we're using for now, or until someone can come up with something shorter to simplify the signs.

Yes, this particular project is Fitwel v2. 

The req's under v2.1 state "Signage that indicates smoking is allowed on site, within a certain distance from doors, windows, or
vent ducts, is not permitted and does not qualify for this strategy."

I'm not sure how they expect projects that are also pursuing LEED to meet this requirement. For our particular project, for example, it is basically a zero lot line circumstance. In our case, banning smoking on the "site" doesn't matter and is not enforceable b/c it's surrounded by public right-of-way. If signage just stated "site" then it wouldn't meet the LEED requirements, which has the 25' standoff regardless of zero lot line or not.

I know this will come up at some point, and assume at that time that we'd have to contact Fitwel and see what their expectations would be.
