See that's the point I was trying to figure and yeah I live in the US. I figured it would be in something like a grey area where you could grow them, but as long as you aren't extracting things from them, it's okay.
AFAIK neither growing aya vines nor extracting their alkaloids is illegal since it is not a controlled substance in USA.
Chacruna looks like any other plant though, to be honest xD
If they wanted to throw a fit about it, many other plants have DMT in them. It would be interesting to watch that case play out, on the off chance I were to be raided for growing chac bushes or something. Just another way the law is made of BS...
