People that use meth often times have sores on their faces. One reason for this is because users often feel like they have bugs under their skin and they obsessively pick at their skin until a sore forms. Also, acne appears on their skin because of poor hygiene and because blood is restricted from the vessels. Along with picking on these acne spots and the hallucination of bugs, sores take longer to heal.
Also, meth users end up with what is called “meth mouth.” This is because meth causes extreme dry mouth and users have an intense craving for very sugary drinks and food. The lack of saliva leaves the mouth free to produce bacteria that eats away at the teeth and gums leaving weak spots that are extra prone to cavities and infections. Many times all of the user’s teeth have to be pulled out–even young users and those that have only been using for a short time.
