MDMA Is a Heart

My name is Marcel and my favorite drug is MDMA. That’s probably not the professionally advisable thing to open with, but it’s true, and it’s relevant context for why I find Meaghan Li’s poster series This Is Your Brain on Drugs unusually convincing.

Li is a graphic designer who visualized what various substances actually do to your neurochemistry as minimalist abstract shapes. MDMA is a heart—warm, rounded, expansive outward. Cocaine is an erratic ascending loop that spikes hard and ends badly. Speed is pure zigzag. The visual vocabulary is doing real descriptive work here, not just aesthetic work: if you’ve taken any of these things, you recognize the shapes immediately.

What I like about them is the absence of judgment. These aren’t anti-drug PSAs with cleaner art direction. They’re portraits—honest, slightly clinical, more interested in accuracy than in warning you away from anything. The cocaine one captures exactly the thing about cocaine that makes it so reliably stupid: the initial confidence of the line, the speed of the escalation, and then the sudden, steep drop that was always going to be there waiting.

The heroin poster is the one I keep returning to. It’s the only shape in the series that looks frightening from the very first stroke—no inviting ascent, no phase where it resembles something you’d want. Just a line that signals descent from the beginning. If you ever needed a single image to explain why heroin is categorically different from everything else on this list, it’s probably that.
