Sniffer dogs can find what ever they are trained to –
some are only trained for explosives some are trained for drugs
It is individual to areas too, as they will train the dogs to smell cutting agents too – and different areas often use different things, I know local dogs in my area were trained on mephadrone (?sp) – they had a load of confiscated stuff and they used this to train the dogs, in 2010, and they do ‘try’ and keep up to date with Rc’s,
usually its cannabis, coke, heroin, methadone, subutex as main drugs the dogs are trained on, but I do think ketamin is also more and more being trained than years before
so I am unable to answer your question with a definite –
