Or, indeed, both. Holmes famously mainlines a 7% solution of cocaine in "The Sign of Four", but the morphine/heroin use was noted too - he was admonished by Dr. Watson over it.

The use of opiates in the stories created a connections with the criminal side of Victorian society - "The Bar of Gold" (I think) was an opium-den where corpses were dumped through a trapdoor into the Thames. The use of chloroform and curare, too, were common themes of criminal behaviour. Morphine was therapeutic, and cocaine, recreational.

Of course, none of that sort of behaviour was actually illegal until 1965, with the passing of the Dangerous Drugs Act.
