These studies suggest snowball sampling is a useful method for accessing hard-to-reach or vulnerable populations in qualitative research, though it has limitations such as nonrandom selection and potential ethical issues.
Snowball sampling is a nonprobability sampling technique often used in qualitative research to identify and recruit participants from hard-to-reach populations. This method relies on initial subjects to refer others, creating a "snowball" effect. It is particularly useful for studying hidden or stigmatized groups, but it also has limitations and ethical considerations.

Snowball sampling is a valuable tool for researchers aiming to study hard-to-reach or hidden populations. It offers practical advantages in terms of cost and efficiency but comes with ethical and methodological challenges. By understanding its variations, ethical implications, and comparison with other methods like RDS, researchers can better utilize snowball sampling to gather meaningful data while addressing its inherent limitations.
