What is the slowest way for drugs to enter the bloodstream?
Skin based absorbtion, if it's even possible with that drug, or oral injestion.
The slowest dog in the world is the Basset Hound. I think a Basset Hound could outrun a Dandie Dinmont Terrier any day (unless the Basset trips on his ears along the way). I vote for the Dandie to be the slowest. Actually, I think a Pekinese will be the slowest. They have more of a waddle than gait.
If you have not consumed drugs in any way and have taken a drug test while menstruating you will not fail. However if you have consumed drugs, depending on how much and often can effect how long they stay in your system. Drugs (including alcohol) can stay in your bloodstream for as few as 1-2 days to as many as 7-8 days.
Can police enter your home if your not at home and is it possible for them to plant drugs in my home when I am on the way to the hospital?
Police may lawfully enter a home by consent, with a search warrant, or in the case of exigent (unusual or emergency) circumstances, such as when they believe a crime is in progress inside. While it is possible for police to enter your home and plant drugs there, just as it is possible for anyone else to do so, the entry would be unlawful.
