What is the difference between MDA and MDMA? Reddit always gives me better than answers than google.

My buddy wants to try MDMA but he said that MDA is somehow safer? I know a ton about MDMA but i’d only ever heard of MDA like twice before.

What are y’all’s personal choice and why?

Idk if my friend even knows much abt MDA lol, I asked him this question and bro goes “It’s like MDMA but it’s a lot cleaner and safer”
