I spent the five happiest years of my life in a morgue. As a forensic scientist in the Cleveland coroner’s office I analyzed gunshot residue on hands and clothing, hairs, fibers, paint, glass, DNA, blood and many other forms of trace evidence, as well as crime scenes. Now I'm a certified latent print examiner and CSI for a police department in Florida. I also write a series of forensic suspense novels, turning the day job into fiction. My books have been translated into six languages.
Hair is just dead cells, so once something is there, it stays there. Hair grows at about 1/2 inch per month, in general (mine, to my frustration, grows much more slowly). So if your hair is longer than say 6 inches, the cocaine will still be there. If your hair is much shorter, then I don’t know what’s happening.Hope that helps.
I suppose that’s theoretically possible, but I wouldn’t think it likely. The saliva would sink into the paper of the money quickly, and then when swabbing the person’s skin you’d have to happen on the exact spot where that tiny bit of saliva transferred to.
I hope that helps!
I'm sorry but I don't know what a FEPAC school is.
That's an awfully broad question. What do you think are the physical and chemical properties? Blood has hemoglobin. Hair grows out of your head. Footprints are impressions in the dirt. I'm pretty sure you could write a good answer to this question yourself.

The job requirements are whatever the hiring agency says they are, so it could be anything from a high school diploma to a PhD in genetics. The only way to know is to call the department or check their website for job vacancies.
I'm sorry, I was sure I answered this long ago! Collecting buccal swabs is very easy--they come in a kit with everything necessary plus instructions for rubbing the swabs on the inside of the mouth and then packaging. Anyone could do it. I've never heard of a case where it was considered contaminated.
Huh, that's a good question. I hope my books show what it's really like, except, of course, that my protagonist spends much more time out of the lab than in it, which is not at all realistic.
The non-fiction TV shows and books show reality, however, you have to remember that they're presenting cases that most investigators may come across once or twice in a lifetime.
Fiction shows, like "CSI" in which they have computerized databases of every substance in the world including toothpaste and wall paint, or ones in which female pathologists wear cocktail dresses to work. are definitely not realistic at all.
