Used for IV injection. Insulin syringes (with cemented needles) are common, but 1-2 mL syringes with short hypodermic needles (0.5 inch (13 mm), and 14-30 G) are also used (e.g. "tuberculin syringes"), meant to penetrate surface veins. | Used for IV injection.

Drug users typically use a 25 g rapid (5-16 seconds) intravenous injection by arm via the median cubital vein to get a [https://en.wikipedia.org/wiki/Rush_(psychology) rush]. However, smaller gauges such as 30 g can be used to prevent a vein collapse for repeated administration. Hypodermic needles smaller than 30 G are normally used for subcutaneous injection, but not for intravenous (coagulated blood immediately after blood response) or intramuscular use (the finest needles are very short). | Drug users typically use a 25 g rapid (5-16 seconds) intravenous injection by arm via the median cubital vein to get a [https://en.wikipedia.org/wiki/Rush_(psychology) rush].
