Drug Testing For Methamphetamines

Methamphetamine is a stimulant drug chemically related to amphetamine but with stronger effects on the central nervous system. It is a white, odorless, bitter-tasting crystalline powder that easily dissolves in water or alcohol. "Meth" is made of highly volatile, toxic substances (based on such chemical "precursors" as methylamine and amyl amine) that are melded in differing combinations, forming what some have described as a "mix of laundry detergent and lighter fluid."

• Methamphetamine is a powerful central nervous system stimulant.

The drug works directly on the brain and spinal cord by interfering with normal neurotransmission. Neurotransmitters are chemical substances naturally produced within nerve cells used to communicate with each other and send messages to influence and regulate our thinking and all other systems throughout the body.

The main neurotransmitter affected by methamphetamine is dopamine. Dopamine is involved with our natural reward system. For example, feeling good about a job well done, getting pleasure from our family or social interactions, feeling content and that our lives are meaningful and count for something, all rely on dopamine transmission.

Ice is the translucent crystal, smokable form of methamphetamine. It is also commonly called glass or crystal and, like other stimulants, is highly addictive. (In terms of molecular structure, ice and methamphetamine are the same) The use of ice results in a longer, more intense high and an enhanced and more rapid onset of the negative effects of other forms of methamphetamine.
