Here's why it's important to be careful with these kinds of assumptions:
* Speculation and Misinformation: It's easy to speculate about an artist's creative process, but it's important to avoid spreading rumors or making claims without evidence.
* Stigma and Stereotyping: Suggesting someone was on drugs can perpetuate harmful stereotypes about creativity and mental health.
* Respect for Privacy: Even if someone's personal life was public knowledge, it's not appropriate to speculate about their drug use.
Instead of focusing on potentially sensitive topics like drug use, it's better to appreciate the creativity and artistry that went into making Adventure Time such a beloved show.
