Why do you want an injection and spanking?
There are many ways of administration, the slowest is oral administration, because it needs to be absorbed through the blood vessels of the stomach to achieve the drug effect, and the fastest is intravenous injection, because it is directly hit on the blood stream, so it is a general drip.

Smack that is an intramuscular injection with moderate action time. Is to inject the drug into the muscle and let the small blood vessels in the muscle slowly absorb it. The common parts of intramuscular injection are the arms and buttocks, and the gluteal muscles are often chosen, because the gluteal muscles are thick and difficult to puncture deep blood vessels. There are many nerves around the buttocks to avoid hurting them. The needles on the buttocks are all on the outside of the unilateral buttocks.
