Edible Uses
The leaves have been made into a drink[257]. Some care should be exercised here. The tea will contain nicotine, and this can be toxic to the body. There is some evidence that Nicotiana glauca may have led to accidental poisoning when it was mistaken for other plants. We would recommend that ingestion is not considered. Please see the warning in Known Hazards.

Plants can survive the winter outdoors in the milder parts of Britain, though they usually act as herbaceous perennials in such conditions[200]. Plants require more than 14 hours daylight per day in order to induce flowering[169].
Propagation
Seed - surface sow in a warm greenhouse about 10 weeks before the last expected spring frosts. The seed usually germinates in 10 - 20 days at 20°c. Keep the soil moist and pot up as soon as the plants are big enough to handle, planting them out after the last expected frosts.

Like F. Goffman said it doesn't contain that much nicotine if any at all, mostly Anabasine.
