Physical Signs of Meth Addiction

Methamphetamine is a highly addictive stimulant that causes an intense rush of euphoria in its users. Meth may be consumed via intravenous injection, by inhalation, orally, or by snorting. According to the National Institute on Drug Abuse, 1.9 million individuals over the age of 12 have tried methamphetamine. In addition to the emotional and behavioral effects of meth addiction, there are severe physical consequences to the consumption of the drug.

Oral Effects

Use of methamphetamines can cause the teeth to become discolored, brittle and even chipped. The term often used to describe the oral effects of meth use is "meth mouth." In those who use meth, the teeth become stained, deteriorate and rot. This could be linked to the toxic chemicals in methamphetamines or side effects of the drug. Meth causes blood tissues to shrink and die, cutting off blood supply to the oral cavity and reducing saliva production, which aids in neutralizing harmful acids in the mouth.

Other Visible Effects

The death of blood vessels causes other visible signs of meth use. Because of the lack of blood flow to body tissue, including the skin, it is difficult and sometimes impossible for the body to repair itself from injury. As a result, the skin loses elasticity, and meth users often look more aged than their chronological years. Sores appear on the skin that may take a prolonged time to heal. In extreme cases, the sores may not heal at all. The sores are often because of skin picking, which is common among meth users.

Internal Effects

In addition to the affects methamphetamines have on the physical appearance, there are serious changes that take place within the body. As reported by Science Daily, a study completed at UCLA Medical center showed meth use can cause permanent damage to the brain, harming the nerve cells resulting in symptoms similar to those seen in Alzheimer's disease, psychosis and dementia. In addition use can cause constriction or destruction of the blood vessels. This can result in increased heart rate and abnormal blood pressure. The kidneys and liver are compromised as well. The toxins in meth are difficult for the liver to break down, and for the kidneys to excrete in urine. This results in low urine output and a higher level of toxins remaining in the body.
