Sam, - Aspergers gives you an excuse to ask questions. The subject is a relevant one to all horse owners, because the effect a 'drug' - a word you perhaps ought to carefully further define - will be on all horses, all stable hands and riders and not just those in the racing industry.
A pharmaceutical is a "drug" , whatever you mean by using the word.
If you mean by 'drug' say 'performance effecting' perhaps with illegal intent then you have one route to pursue - if you mean by side effect from a medication, you need to speak with a veterinarian.
Think, by drinking a strong beer whilst tapping away on the computor - you have taken a 'drug' namely 'alcohol'.
The subject is worth pursuing and I have never seen a book outlining the dangers.
Then once you have exhausted the technical books about medications, go speak with a herbalist and talk about the weeds to be found in a hedgerow.
That's quite a subject you have picked for yourself.
