Blood Toxicology

by Los
(NY)

I'm a writer who's penned a crime scenario and would like to know:

If a victim injected himself with a paralytic agent with a short half life, such as Ketamine, or Vecuronium...

and then slit their wrists, bleeding heavily from the wounds and dying from sanguination...

would the blood that secreted from the veins shortly after ingesting the paralytic agent, (or any of the blood that flowed out)...

hold trace evidence of the paralytic agents?

or would the agents dissolve in the expelled blood, say after a day had passed?

Would inhaling powdered forms, or liquid ingested, change or alter the outcome?

please let me know, thank you
