The term drug has become derogatory for most have negative associations with that word due to the programming in today's society.

I prefer the term Hallucinogenic researcher as to me such things are a form of self exploration and can truly be enlightening if the individual participating in taking the substance is open to such ideas and concepts.

Of course everyone is different, but one substance in particular that has been invaluable to me is LSD.

Which for those who are unaware, is derived from a plant as well through a biological chemical process.
