It's 100% about drugs, as he says “iowaska" in the song. As per lyrics genius:

Iowaska, more commonly known as “Ayahuasca”, is a brew which originated from South America. It is primarily taken for its dimethyltryptamine (DMT) contents which is said to enable people to separate their soul from their earthly body, experiencing outstanding trips. DMT is essentially a very basic compound which results in a rapid metabolization by the Human body. However, people still report trips that feel like hours or days. The thought behind the Ayahuasca brew is a mixing of DMT-rich plants with plants that contain compounds that inhibit the Human body to metabolizae DMT, resulting in experiences that reportedly feel like months or years. The brew goes back to Indigenous people in Peru and neighboring countries.

There is strong evidence that DMT is an endogenous compound which is said to be produced in the pineal gland. It is often linked to near-death experiences (NDE).

“Bullet train to Iowaska/ayahuasca” has a touch of irony, because the concept of time might not be real in the context of DMT-fueled experiences, yet Maynard uses the image of rapidly approaching the ayahuasca brew. The “soon” at the end means a delay, which is another theme of time,
