Ibsen's contemporaries found the play shocking and indecent, and disliked its more than frank treatment of the forbidden topic of venereal disease. At the time, the mere mention of venereal disease was scandalous, and to show that a person who followed society's ideals of morality was at risk from her own husband was considered beyond the pale. According to Richard Eyre, "There was an outcry of indignation against the attack on religion, the defence of free love, the mention of incest and syphilis. Large piles of unsold copies were returned to the publisher, the booksellers embarrassed by their presence on the shelves."
Upon being produced in England in 1891, the play was reviled in the press. In a typical review at the time, The Daily Telegraph referred to it as "Ibsen's positively abominable play entitled Ghosts.... An open drain: a loathsome sore unbandaged; a dirty act done publicly.... Gross, almost putrid indecorum.... Literary carrion.... Crapulous stuff".
When Ghosts was produced in Norway it scandalised Norwegian society and Ibsen was strongly criticised. In 1898 when Ibsen was presented to King Oscar II of Sweden and Norway, at a dinner in Ibsen's honour, the King told Ibsen that Ghosts was not a good play. After a pause, Ibsen exploded, "Your Majesty, I had to write Ghosts!"
