Why do I like the smell of new plastic?

…or new houses, new cars, dry erase markers, gasoline, inflatable pool toys?

The “smelly chemical” is the VOC benzene, and other, similar, hydrocarbons. They’re carcinogenic! So why would we like the smell of them?

Two main theories:

Theory 1: smelling benzene releases dopamine, the reward chemical in our brains. It temporarily suppresses our nervous system, not unlike alcohol, causing us momentary euphoria.

Theory 2: smell is the only sense that goes directly to the emotional center in our brains. If we have good childhood memories of fresh plastic, it may activate the same response.

So, if you love the smell of new plastic at home, you’re not alone! Air it out, and enjoy responsibly.
