you can't force someone to see anything your way. just drop the debate after you state your facts. say "end of story, end of debate, I cant help you open your eyes if you force them shut." then drop it yourself, except for talking about an experience whenever you trip. curiosity will eventually set it if that person wants to delve into the world.

everyone's experiences with anything is entirely relative, and it makes sense that a drug that digs deep into your subconscious (think of religious indocrination - don't make that negative - you experienced as a child with your parents) will make you have a "religious or spiritual awakening"

however that is just my 2 cents
