Background: Despite the rising prevalence of methamphetamine use disorder (MUD) among adolescents and its severe consequences, data on hematological inflammatory indices in this population remain limited. Objectives: This study aimed to evaluate systemic inflammatory markers in adolescents with MUD and their associations with addiction severity. Methods: The retrospective case–control study included 44 adolescents with MUD and 44 age- and gender-matched healthy controls. Hematological indices were calculated from complete blood count data, including neutrophil-to-lymphocyte ratio (NLR), derived NLR (dNLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), Basophil-to-lymphocyte ratio (BLR), systemic immune-inflammation index (SII), systemic inflammation response index (SIRI), and aggregate index of systemic inflammation (AISI). Group comparisons, receiver operating characteristic (ROC) analyses, and partial correlations were performed. Results: The MUD group included 30 females (68.2%) and 14 males (31.8%); the control group included 25 females (56.8%) and 19 males (43.2%). Adolescents with MUD showed significantly higher neutrophil and platelet counts, NLR, dNLR, PLR, MLR, SII, SIRI, and AISI, alongside reduced lymphocyte counts, compared with controls (all p <.05). ROC analyses revealed good discriminative ability for SII (AUC = 0.79), AISI (AUC = 0.73), and SIRI (AUC = 0.69). Several indices, including NLR, PLR, and SII, correlated negatively with treatment motivation, while PLR and MLR correlated positively with diagnostic severity. Conclusions: Adolescents with MUD demonstrate marked systemic inflammatory alterations detectable through routine hematological indices. These markers may serve as low-cost, clinically accessible biomarkers for identifying high-risk individuals and monitoring disease severity, with implications for early intervention and personalized treatment.
