Where does one locally get herbs that are used for Changa?

I'm specifically interested in trying caapi, passionflower, or mullein.

What are the legal status of each in US? As in can I call up my local herb/healthfood store and ask if they sell these?

The passionflower and mullein you should be able to find at a local herb shop. We are not allowed to discuss the sourcing of caapi leaf, so you'll have to figure that one out for yourself.

All of the above are completely legal in the United States.

Check the guide to the enhanced leaf on the changa sub-forum
