S5·E1 Where There's Smoke

Struggling to remain sober, Cheyenne starts taking pills that will make her violently ill if she drinks alcohol. When Reba throws a party for her real estate clients, Van and Cheyenne go to great lengths to try and stop Reba from drinking after she accidentally takes one of Cheyenne's pills, thinking it's a vitamin. Meanwhile, ex-smokers Brock and Barbra Jean lecture Kyra and Jake on the dangers of smoking, but that doesn't stop Brock from secretly lighting up.
