Nicotiana glauca is a plant that is related to tobacco. It has really long, skinny leaves like a green straw that grow on a tall stem. The stem can grow up to 30 feet (9 meters) tall, which is taller than the tallest person in the world!
This plant is also known as tree tobacco because it grows into a big tree in some places where it likes to live, like in South America and parts of North America.
People have been using this plant for a long time as a medicine to help with things like pain and breathing problems. Some people even use it for spiritual purposes, like in traditional ceremonies.
But it's important to remember that smoking any kind of plant or tobacco is bad for your health and can cause serious problems like lung cancer and heart disease. So it's best to just admire this plant from afar and not use it in any way that could harm you.
