True or False: It is more common to encounter single drug users than polydrug users.

The assertion is false because, in practice, it is often observed that polydrug use is more prevalent than single drug use. Many individuals who use illicit substances tend to use multiple drugs simultaneously or in a sequence, which complicates the patterns of substance use. This trend may be influenced by various factors, including the desire to enhance the effects of a primary substance, mitigate withdrawal symptoms, or counteract the side effects of a particular drug.

Research and data consistently indicate that polydrug use poses various risks and challenges for law enforcement and public health, revealing a more complex landscape of substance use than simply encountering users of single drugs. While there may be variations based on specific demographics or regional substance use trends, the broader and more generalized observation is that polydrug use is indeed more common than isolated use of a single substance.
