Methamphetamine is often dissolved in water (liquefied) for the purposes of transportation. It tends to be placed in familiar containers (e.g., liquor bottles) which are commonplace at points of inspection (e.g., ports of entry). Once shipped to its destination, the water is boiled away, leaving the drug in solid form. This stated, there have been reports of some consumers preferring the drug in liquid form. Examples of liquid methamphetamine are shown in the side bar.
