Methamphetamine affects your brain in many ways. In the short term, meth causes emotional changes such as anxiety, euphoria, and depression. Long-term effects include chronic fatigue, paranoid or delusional thinking, and permanent psychological damage.

Methamphetamine affects your body by creating a false sense of energy. The drug pushes the body faster and further than it’s meant to go and increases heart rate, blood pressure, and risk of stroke.
Methamphetamine affects your self-control. Meth is a powerfully addictive drug that can cause aggression and violent or psychotic behavior. An overdose of meth can result in heart failure. Long-term physical effects such as liver, kidney, and lung damage can also kill you.

Methamphetamine is illegal in all states and highly dangerous; get the facts. For example, the toxic nature of the chemicals used to produce meth can cause fires, produce toxic vapors, and damage the environment. Another fact is that in 2001, meth use sent more people to the emergency room than use of any other club drug. Over half of these cases involved meth in combination with another drug, such as alcohol, heroin, or cocaine.

There are a lot of risks associated with using methamphetamine, including irreversible damage to blood vessels in the brain and the risk of acquiring HIV/AIDS for Meth users who inject the drug and share needles.
