From the Academy of General Dentistry:
Methamphetamine , a sympathomimetic amine, acts on alpha adrenergic receptors of salivary gland vasculature, producing vasoconstriction and reducing salivary flow.
Translation for patients:
Meth reduces the blood flow in saliva glands which reduces the amount of spit produced. This increases the probability of getting cavities.
