Participants will be randomized to either avoid flavored RTD alcoholic beverages or continue their usual alcohol consumption.\n\nPrimary outcomes include feasibility, adherence, acceptability. Secondary outcomes include preliminary efficacy of flavored RTD restriction on alcohol consumption and e-cigarette use measured through daily electronic diaries; biomarkers of alcohol and nicotine exposure, including urinary ethyl glucuronide (EtG), urinary cotinine, and blood phosphatidylethanol (PEth).",[28,29],"E-cigarette","Alcohol",[29,31,28,32,33],"Ready-to-Drink Alcohol","Vaping","Alcohol Restriction","NOT_YET_RECRUITING","2026-09-25",{"date":37,"type":38},"2026-09-30","ACTUAL",{"date":40,"type":22},"2026-10",{"date":42,"type":22},"2027-08",{"name":44,"class":45},"Medical University of South Carolina","OTHER"]
