For medical marijuana patients searching for the perfect treatment regimen, symptom relief without unwanted side effects is ideal. Medical marijuana is praised for treating a variety of conditions without producing severe adverse side effects, but some mild side effects are possible. One such side effect is dry mouth, which results when the cannabinoid THC binds to receptors in the salivary glands and reduces gland activity. Because of this, marijuana is acting directly on the salivary glands and therefore the side effect is not the result of any one particular vehicle of administration. Dry mouth is thought to be dose dependent, and becomes more severe with more consumption. To avoid dry mouth, patients should attempt to use the minimum dose required to produce symptom relief. If dry mouth does occur, drinking water through a straw can help stimulate the salivary glands.
