Johhny, if it is that one herbal drug I'm thinking- (not mentioning the name) I would not smoke it- I would dry the leaves and make it into a tea and drink it. Smoking anything- wether tobacco, herbs, etc., is going to hurt your lungs and anything "mind expanding" is going to hurt your mind if overdone, since you're mind also needs grounding as well. There's always a catch to those types of mind altering things. We humans never get the right balance.
Making it into a tea and drinking it would probably truly help your entire body out– that particular herb has alot of anti-oxidants and if not illegal- would be the most nutritious herb anyone can take if eaten. Everything that the Great Spirit created is valuable on this Earth- Just that we humans abuse and corrupt these things and end up making them into something toxic. Or else we smoke it instead of eating it (or drinking as a tea) as was probably originally intended to be used.
I would never get any of this drug from any dealer- They add things that they don't tell people– it's not pure. In most states it's illegal as well- so you have to make sure that you are not breaking the law.
If you come upon any of this plant by accident- I would use the leaves–dry them and make into a tea. Some herbs like that also have a calming mind altering effect- (though much slighter) when drunk as a tea.
hugs and be careful!
