Researchers have synthesized a new psychedelic capable of treating depression — without the hallucinations typically associated with psychoactive drugs, according to a recent study published in the journal Nature.

Recent advances with psychedelics like ketamine have hinted at a powerful potential for treating mental health conditions like anxiety, addiction, and depression. But psychoactive drugs can — as the name implies — have substantial side effects.

Beyond the hallucinations — which are both loved and scorned, depending on the expert — there are other possibly harmful side effects, like cardiac toxicity.
