Origen de la bandera roja

DefiniciónHabitual use of smokeless tobacco products — chewing tobacco, snus (oral nicotine pouch with tobacco), snuff (dry, moist, dipping tobacco), gutka/pan masala (South Asian preparations with areca nut + tobacco). IARC Group 1 carcinogen (Monograph 89, 2007; reaffirmed Monograph 100E). Causally linked to oral cavity cancer (tongue, gum, buccal mucosa, floor of mouth — particularly at the placement site), esophageal cancer, pancreatic cancer (RR ~1.5-2.0 in Northern European snus cohorts; meta-analyses Boffetta + Hashibe 2008). Risk of oral cancer markedly elevated in South-Asian gutka/pan masala users — RR up to ~10 with combined tobacco + areca nut + lime. Cessation reduces risk over time but not to baseline non-user levels; oral mucosa changes (leukoplakia, erythroplakia) can regress with cessation. Prevention-persona RedFlag (§20 v0.3 lifestyle expansion).

STUB pending two-Co-Lead signoff per CHARTER §6.1 dev-mode.
