 So Bancroft's and Liversidge's unfortunate experimental animals may have been injected with extracts of "Duboisia hopwoodii" high in the toxic nornicotine, while the specimens they sent to Europe for assessment (collected from different locations at different times) contained the more benign nicotine and little or no nornicotine.The reports of animal poisonings probably relate to the consumption of "Duboisia hopwoodii" high in nornicotine.In central Australia, various species of wild "Nicotiana", not "Duboisia hopwoodii", are used.
