The aim of this study was to determine whether perception of risk and accessibility of cannabis predicted the age of initiation of cannabis use among Jamaican secondary school students. Data from a nationally representative sample were analysed. Descriptive statistical analysis was done while binary logistic regression was used to compute point estimates and confidence intervals (CIs). The median age of initiation was 13 years. Gender was a predictor of age of initiation, with females having

There was a significant inverse association between grade level in school and age of initiation of cannabis use, with 11 th grade students having a significantly reduced risk of commencing cannabis use at the age of 13 years or younger (COR: 0.41; 95% CI: 0.23, 0.70; AOR: 0.41; 95% CI: 0.23, 0.72). Participants who perceived cannabis use as moderately harmful were 67% less likely to initiate cannabis use at the age of 13 years or younger compared to participants who thought it was not harmful (AOR: 0.33; 95% CI: 0.12, 0.88). Perceptions of access to cannabis did not predict age of initiation of cannabis use. Being female, being in the 11 th grade and the perception that cannabis use was moderately harmful significantly reduced the risk of initiating cannabis use at the age of 13 years or younger. RESUMEN El objetivo de este estudio fue determinar si la percepción del riesgo y la accesibilidad al cannabis predecían la edad de iniciación del uso de cannabis entre los estudiantes de escuela secundaria en Jamaica. Se analizaron los datos de una muestra nacionalmente representativa. Se realizó un análisis estadístico descriptivo, y se utilizó una regresión logística binaria para computar las estimaciones puntuales y los intervalos de confianza (IC). La edad promedio de iniciación fue de 13 años. El género fue un predictor de la edad de iniciación, presentando las hembras un riesgo 39% menor de iniciar el uso de cannabis a la edad de 13 años o más joven,
