The effectiveness of cacao as a psychological elevator hasn’t been established yet, but, according to the following sources it appears there is evidence to support the assumption that snorting chocolate gets you high:
Exactly how effective cacao is at getting people high has not yet been established, although there are a number of reasons why it might work. For starters, it contains endorphins as well as a chemical called tyrosine, which is a precursor to dopamine. Since both endorphins and dopamine are natural neurotransmitters known to induce feelings of pleasure, it’s unsurprising that people have been reporting that snocolate helps to elevate their mood.
Cacao is also rich in antioxidants such as epicatechin, which increases blood flow to the brain and the muscles, giving people both a physical and an emotional kick that could help them dance for longer. Since epicatechin has also been shown to protect neurons and improve cognitive function, this is clearly a preferable option to other dance-fueling substances like cocaine and MDMA, even though cacao is unlikely to match the high generated by these drugs.

The chemistry behind cacao’s buzz is that it contains endorphins as well as tyrosine. Tyrosine is a precursor to dopamine, which fuels the body’s pleasure/reward system. The dopamine receptors in our brains are also the same system that opioid-related drugs, including heroin and Oxycontin, react with for their intoxicating and addictive properties.
Both dopamine and endorphins produce pleasure, so the reported effects of chocolate powder sniffing causing euphoria are not without merit, or science to back them up. While the practice hasn’t been scientifically researched for safety, “snocolate” as it is now being referred to certainly isn’t cocaine or heroin, and as widely accepted as chocolate is in modern culture, it isn’t likely to go away anytime soon.
