I've smoked tobacco for 30-ish years. Organic, additive-free tobacco is definitely less problematic for me. Lately I've been growing my own Nicotiana Rustica [0], which contains plenty more nicotine than regular tobacco but is nowhere near as addictive.

I know what I would do if I was selling drugs and didn't give a crap about anything but profits, I would make them as addictive as possible.

How do you find the Rustica? I wanted to have a crack at growing it in my entheogen garden

Before I started growing rustica; I ordered a roll of real mapacho from south america, which was very nice.

I've only tried sun-dried leaves from my own garden yet, which isn't quite as exciting. The nicotine boost is still the same though.

The idea is to grow enough to make my own mapacho paste and ferment a roll for a while.

By itself it's pretty harsh, and trippy because of the nicotine. I prefer it mixed with Cannabis and/or regular tobacco.

They need nutrients, lots of nutrients (epsom salt works like magic). And loose, sandy soil or the initial roots won't go anywhere.

Seeds are available at most 'ethnobotanical' online stores. Tiny seeds: can get hundreds for a few bucks. Pretty easy to grow too.
