The toxicology results were pending, the statement added.
Forensic scientists generally specialise in a certain area of research, such as body fluids or toxicology or, in the case of Sheridan, textile fibres.
"Right now, it's being investigated like a homicide," Hampton said, adding that both drivers will undergo standard toxicology tests.
In Scotland alone, they were discovered during toxicology reports into 36 deaths.
Ideally, toxicology studies would be completed earlier in the process, but so far that has proven difficult.Evidently there is no shortage of new ways to generate and evaluate drug candidates.
The result is likely to be about 4m toxicology experiments that would not otherwise have happened.This extra testing may or may not be good in principle, but it is likely to lead to chaos in practice.
Software can be used to design compounds with favourable properties, but toxicology is difficult to predict computationally.
Whether devising medicines or insecticides, scientists also use high-tech facilities in combinatorial chemistry.AstraZeneca's drug and agriculture businesses also have joint projects in toxicology: just as pesticides must poison pests, not the diner, so drugs must kill bugs, not the patient.
