its Snuff

To determine which tobacco product is probably being used if there is no visible smoke in a restaurant where smoking is not allowed, we can analyze the options given:

1. Cigar: Cigars typically produce visible smoke when they are lit and being smoked. Therefore, it is less likely to be the source of the tobacco smell without any smoke being present.

2. Pipe: Similar to cigars, pipes also produce visible smoke when they are in use. Therefore, it is also less likely to be the source of the smell without any smoke being observed.

3. Snuff: Snuff is a smokeless tobacco product that is typically inhaled or sniffed through the nose. It does not produce visible smoke. Given the scenario and the absence of smoke, snuff seems like a plausible answer to this question.

4. Water pipe: Water pipes or hookahs do produce visible smoke when they are used, so they might not be the correct answer in this context.

Considering all the possibilities, snuff seems to be the most likely tobacco product being used in a scenario where no smoke is present.
