It's tricky talking about drugs that are illegal and that can be harmful, but can also be highly beneficial and safe when taken under the right conditions. Let's try to avoid blanket condemnations and moralising; HN is meant to be a place for more nuanced discussions than that.
MDMA has for several decades been widely reported, anecdotally, to bring about profound, lasting, changes in people's emotional states, and to set them on long-term journeys of personal growth. And in recent years many governments around the world have green-lit medical trials into its benefits for various kinds of emotional/psychiatric conditions, though of course few people have access to these trials.
So, let's not be so dismissive of someone being open enough to share their personal experience.
