What Is Cotton Mouth?
Cotton mouth (dry mouth) is a common side effect of cannabis where THC temporarily reduces saliva production, causing a dry, parched feeling.
Cotton Mouth Explained
Cotton mouth (xerostomia) is one of the most common side effects of cannabis consumption. It occurs because THC binds to cannabinoid receptors in the salivary glands, temporarily reducing saliva production. This creates a dry, sticky, uncomfortable sensation in the mouth and throat. Cotton mouth happens regardless of consumption method — smoking, vaping, edibles, and tinctures can all cause it. It is temporary and not harmful.
Why It Matters
Cotton mouth is virtually universal among cannabis users. Staying hydrated and having water or beverages nearby is the simplest and most effective solution.
