^aTotal smoking (S) and/or nonsmoking (NS) capacity estimated assuming maximum of 6 patrons per game table, 10 patrons per poker table, and 1 patron per slot machine. The number of slots, table games, and poker tables were determined by our on-site (firsthand) observations in the present study.
^bMain Area capacity refers to smoking (S) low-stakes slot machines and table games (i.e., excluding poker tables and high stakes slots). The Main Area gaming capacity (low stakes slots + tables) is a quantity used in the present work to calculate relative occupancy between nonsmoking and smoking areas. The occupancy for non-main smoking areas (poker or high-stakes slots/tables) can be calculated by subtracting the Main Area capacity from the Total capacity.
^cExcept for Casino I, which had 10 table games, nonsmoking capacity refers to the number of slot machines in nonsmoking areas.
