Drugs and Spiritual Growth

[HTTP]

Fellow totseans, I propose a question and a statement. Do you believe certain psychedelic drugs (LSD, Cannabis, Mescaline...etc) hinder or catalyze spiritual growth? Perhaps both?
I understand this is a similar thread to the marijuana is spiritual thread but I would like to hear your specific opinions on this.

My opinion is this: Drugs are a tool for us to use. I believe that the way we use them are completely based on our intention, and state of mind. Let me use this metaphor. Think of the drug as a hammer.

Now, you can do multiple things with a hammer, for instance, fix a floorboard, or smash someones skull to pieces. Depending on what you intend to do and act on determine the outcome. You could have either made your floor sturdier, or destroyed someones life.

Drugs could be used the same way. If you take something to get "fucked up" that is what is going to happen. If you use it to help widen your conscious, then that is what will happen.

Do you agree/disagree with me? And what is your own personal opinion?
