Forensic Hair Toxicology and Chloroform Results

Here is a scenario for my questions: Lets say someone repeatedly, several days a week over 8 weeks inhales chloroform, and then they die from an overdose in a small sealed area like a closet or car trunk filled with chloroform vapors.


Can forensics tell if chloroform was used over a period of time? Would chloroform specifically be inside the hair, or just coating it, and can forensics tell the difference?

Can chloroform be found in hair toxicology testing from a body that is found 6 months after death, and has been exposed to the elements?
