What is a characteristic feature of amphetamines?

Amphetamines are commonly found in the form of pills or crystallized powder, which is a defining characteristic of this class of drugs. These formulations make amphetamines easily recognizable and distinct from other substances, such as opioids which may present in different forms, or marijuana which is typically a green leafy substance. The crystalline form allows for various methods of consumption, including ingestion or inhalation, and is associated with the stimulant effects of the drug. This characteristic helps law enforcement and medical professionals identify amphetamines in various contexts, such as in drug-related incidents or during drug testing. Understanding these characteristics is crucial for proper identification and management in various situations involving illicit substances.
