It is a dangerous and highly addictive drug that can cause serious short-and long-term health complications, including overdose. In addition, since it is so powerful, even small amounts of meth can quickly result in physical dependence and addiction. Manufacturers originally developed methamphetamine from amphetamine and used it in nasal decongestants and bronchial inhalers.

Today, only one legal meth product exists, called Desoxyn. Doctors may prescribe it to help with weight loss or treat attention deficit hyperactivity disorder (ADHD) symptoms in some limited circumstances. People now make or “cook” meth in crude laboratories using various over-the-counter drugs and highly corrosive chemicals.

The most common method uses pseudoephedrine or ephedrine, which are ingredients in many cold remedies. Cooking meth is highly dangerous because the fumes from the chemicals used are extremely toxic. They can lead to explosions and fires.

How long does it stay in the system
Meth has long lasting effects, and it may take up to 4 days to leave the body. Its half-life is around 10 hours. This means it takes the body about 10 hours to metabolize and eliminate half of the ingested amount from the bloodstream.

The body metabolizes and eliminates methamphetamine in the liver and kidneys. In the liver, an enzyme called cytochrome P450 2D6 breaks it down into two primary metabolites: para-hydroxymethamphetamine (pOH-MA) and amphetamine (AMP). The kidneys then filter these metabolites out of the blood and expel them in the urine.
