how to grow/dry tobacco?

So this summer I planted a flowering tobacco, and since it had huge prolific leaves anyway, decided to harvest and dry some leaves for a smoker friend of mine. So my first question is: can Any tobacco be smoked or is there just one species?

Also, it was kind of difficult to dry, its sticky. And I'm sure I'm not 'curing' it, I just left it on a table in a dark room till it turned crispy brown. But, second question: how do I actually dry it if its going to be smoked?

And then, I have a client who's interested in growing it in an edible hedge. So, since I want this planting to be a bit more professional, I did an internet search which came up with 'Nicotiana langsdorffii' as 'Tobacco' and  not 'Flowering Tobacco', does that mean it's The One? But, alas, I didn't find much about growth habit, when to harvest, etc associated with this particular species. Is it not the one?
Any suggestions?

There are different varieties of tobacco, some tastier than others. Here's a source for some smoking tobacco varieties (see Nicotiana):
