It’s a tempting theory – after all the story has Alice eating ‘magic’ mushrooms and meeting hookah smoking caterpillars. However, most experts agree that while the tale is weird, it is simply excellent fanciful writing and there is no evidence to suggest Carroll was a drug user.

According to Dr. Heather Worthington of Cardiff University, there is a strong possibility that people are attributing the story to psychedelics mainly because it was written during an era when its use was rampant, not necessarily because Carroll was actually under the influence of anything.
