Based on the provided information, it's impossible to definitively say which country is "no smoke" in the sense of having a complete ban on all smoking and e-cigarette use everywhere. The reference material focuses on e-cigarette bans and restrictions in sports venues. However, we can analyze the data to see which countries have the most comprehensive restrictions:
- Finland: Complete ban on e-cigarettes but only partial ban on smoking in sports venues.
- France: Partial ban on e-cigarettes and partial ban on smoking in sports venues.
- Germany: No ban on e-cigarettes but partial ban on smoking in sports venues.
- Greece: Complete ban on e-cigarettes and complete ban on smoking in sports venues.
Therefore, Greece appears to have the most comprehensive restrictions on both e-cigarettes and smoking based on the data provided, with a complete ban in both categories specified (e-cigarettes and sports venues/stadiums). It is important to note that this data focuses only on these two specific areas and doesn't account for other potential smoking restrictions.
