What term is used to describe the smokeable form of meth?

The term that describes the smokeable form of methamphetamine is "ICE." This form of meth is a crystalline structure that has a much higher purity than other forms, allowing it to be smoked. When inhaled, it can produce immediate and intense effects, which contributes to its popularity among users.

While other options like "rock" or "crystals" might initially seem related due to their physical forms, they don't specifically denote methamphetamine as ICE does. "Powder" refers to a different form of meth that is not typically smoked and has different chemical properties and user experiences. Thus, ICE is specifically recognized within substance use terminology as the form that can be smoked, making it the correct choice in this context.
