Hey there ! That's a wonderful idea... Well someone already offered you to grow cannabis so I won't say it !
However for all the people out there that want to smoke something less harmful than cigarette, try to grow these plants, they can be smoked and turned into an herbal mix.
I personally like to use it as a blend with my spliffs. I spent 20 years of my life as a heavy cigarette smoker and nicotine addict so it feel so good to not have that craving no more , and replacing it with a healthier choice.
Here ara the plants that you can grow :
Mullein: Flowering plant in the figwort family Scrophulariaceae. They are native to Europe and Asia, with the highest species diversity in the Mediterranean.
It actually helps people with respiratory conditions. You don't have to smoke it to get the full effects . A tea or eating the flower will have the same calming effect on your lungs
-Catnip : is a species of the genus Nepeta in the family Lamiaceae, native to southern and eastern Europe, the Middle East, central Asia, and parts of China.
Don't smoke too much of it as it gives a headache. Its well known health benefit is the calming effect that it can have on the body.
-Rasperry Leaves: I discovered this herb when my wife got pregnant the first time around.Raspberry leaf tea has been used for canker sores, cold sores, and gingivitis in persons of all ages and anemia, leg cramps, diarrhea, and morning sickness in pregnant women, and as a uterine relaxant.
Works like a charm in a tea :)
Sage : Ahhhh the good old sage. I could say so much about it, but you know what ,just read the health benefits I've found on google about it:
Sage is used for digestive problems, including loss of appetite, gas (flatulence), stomach pain (gastritis), diarrhea, bloating, and heartburn. It is also used for reducing overproduction of perspiration and saliva; and for depression, memory loss, and Alzheimer's disease.
Good luck on finding what you want to grow this year, i hope it helps.
Special mentions: Korean Ginseng, lemon balm, mugwort, and skullcap
