A stupefying beverage is made from the leaves and roots
[2].
Material uses
There are no material uses listed for Datura inoxia.
All parts of the plant are anodyne, antispasmodic, hallucinogenic, hypnotic and narcotic
[3][4]. It has been used in the past as a pain killer and also in the treatment of insanity, fevers with catarrh, diarrhoea and skin diseases
[4]. The plant contains several alkaloids, the most active of which is scopolamine
[4]. This is a potent cholinergic-blocking hallucinogen, which has been used to calm schizoid patients
[5]. The leaves contain 0.52% scopolamine, the calices 1.08%, the stems 0.3%, the roots 0.39%, the fruits 0.77%, the capsules 0.33%, the seeds 0.44% and the whole plant 0.52 - 0.62%

Propagation
Sow the seed in individual pots in early spring in a greenhouse
[1]. Put 3 or 4 seeds in each pot and thin if necessary to the best plant. The seed usually germinates in 3 - 6 weeks at 15°c. Plant out in late spring or early summer, after the last expected frosts.
Especially in areas with hot summers, it is worthwhile trying a sowing outdoors in situ in mid to late spring.

Cultivation
Prefers a rich light sandy soil
[6] and an open sunny position
[1]. It is best grown in a fertile calcareous soil
[1].
Plants are not very cold-hardy, tolerating temperatures down to about -5°c[7]. Plants can be grown outdoors as half-hardy annuals, starting the seed off in a greenhouse.
This species is extremely susceptible to the various viruses that afflict the potato family (Solanaceae), it can act as a centre of infection so should not be grown near potatoes or tomatoes[1].
This species is a commercial source of the alkaloid scopolamine, used in the pharmaceutical industry
[4].
