Chronic tobacco consumption, identified as Tobacco Use Disorder (TUD), is a public health problem. We present a case report of a 37-year-old Brazilian male diagnosed with TUD at age 26, with no comorbidities, that presented visual improvements (i.e., lower thresholds and better discrimination) after nicotine gum administration. Here, we assessed contrast sensitivity and chromatic discrimination using the Metropsis and the Cambridge Colour Test, respectively. Results showed lower thresholds for both visual tasks after the use of nicotine gum. Even considering this is a single case report, our intent is to open new avenues for research involving smoking, addiction and the use of nicotine gum as a replacement tool or adjuvant tool for improvement of visual and/or cognitive processing. It is well known that nicotine gum has protective effects for some diseases, and improves some cognitive functions. However, unclear were its effects on visual processing of people with TUD.
慢性烟草消费，即烟草使用障碍（TUD），是一个公共卫生问题。我们报告了一例 37 岁的巴西男性，他在 26 岁时被诊断出患有 TUD，没有合并症，在使用尼古丁胶后视力有所改善（即阈值降低，辨别力提高）。在这里，我们使用 Metropsis 和 Cambridge Colour Test 分别评估了对比敏感度和色觉辨别力。结果显示，使用尼古丁胶后，两种视觉任务的阈值都降低了。尽管这只是一个单一的病例报告，但我们的目的是为涉及吸烟、成瘾以及使用尼古丁胶作为改善视觉和/或认知处理的替代工具或辅助工具的研究开辟新的途径。众所周知，尼古丁胶对某些疾病具有保护作用，并改善一些认知功能。然而，其对 TUD 患者的视觉处理的影响尚不清楚。
