How many syringes or needles can be obtained in a single purchase without a prescription?

The correct answer is based on New Hampshire's regulations regarding the sale of syringes and needles. In New Hampshire, individuals can purchase up to ten syringes or needles without a prescription. This regulation is designed to ensure access for individuals who may require syringes for legitimate medical uses, such as insulin administration or other necessary injections, while also attempting to prevent misuse or abuse associated with the acquisition of these items.

The law reflects a balance between accessibility for those who need syringes for medical purposes and a framework that discourages potential abuse. Thus, the limit of ten is specifically set to allow sufficient quantity for personal medical needs without necessitating a prescription, but still imposing a restriction to curb illegal activities.

Context around the other options shows that limits beyond ten syringes or needles do not align with New Hampshire's legal requirements. Therefore, the specific regulation on the procurement of syringes or needles emphasizes the importance of maintaining a public health standard while ensuring that responsible access is granted to those in legitimate need.
