Core Viewpoint - The Shanghai Narcotics Control Committee clarified that claims linking a certain milk tea brand to drug-like effects due to caffeine are incorrect, emphasizing that caffeine is naturally occurring and regulated for safety [1] Group 1: Caffeine and Its Sources - Caffeine is a natural alkaloid found in tea leaves, with a higher concentration (2%-5%) in dried tea compared to coffee beans (1%-2%) [2] - Various teas have different caffeine content, with black tea averaging 40-50 mg per 200-250 ml, while green tea averages 20-30 mg [3] - Common foods like chocolate and carbonated drinks also contain caffeine, with dark chocolate (≥70% cocoa) having 80-120 mg per 100 grams, and a 330 ml can of cola containing 30-40 mg [4] Group 2: Caffeine Consumption Guidelines - The recommended safe caffeine intake for healthy adults is 400 mg per day, while for individuals under 18, it is about 175 mg [5] - A 60 kg adult can consume approximately 969 grams of liquid coffee or 1524 grams of liquid milk tea daily without exceeding safe caffeine levels [5] Group 3: Caffeine Sensitivity and Risks - Pregnant women and breastfeeding mothers should limit caffeine intake due to potential effects on fetal development and infant health [6] - Individuals with gastrointestinal issues, high blood pressure, or heart rhythm disorders are advised against high caffeine consumption due to its stimulating effects [6] Group 4: Milk Tea Caffeine Content - Some milk tea brands use whole tea leaves instead of tea powder, resulting in caffeine content in a 500 ml serving potentially exceeding that of a similar volume of coffee [7] - For example, a 470 ml tea drink from a specific brand contains 90-160 mg of caffeine, while a latte has about 100 mg and an Americano around 150 mg [8] - The industry is considering implementing a "red-yellow-green light" system to indicate caffeine levels in beverages, aiding consumer awareness [8]
