[Green tongue phenomenon, or diagnosis via Google].

BACKGROUND

Regular cannabis use may be associated with several oral changes not usually identified by dermatologists: xerostomia, increased risk of caries, periodontitis, leukoedema, gingival hyperplasia, and higher prevalence and density of Candida albicans, leukoplakia or gingivitis.

PATIENTS AND

METHODS

We report herein the appearance of a characteristic green tongue in a patient following intensive marijuana inhalation.

DISCUSSION: This complication has rarely been reported in the medical literature. Paradoxically, it is clearly described in different Internet search engines, particularly Google.
