Yes, it does include illegal drugs. I understand what you are saying dreamer. I believe that illegal drugs such as ecstasy are dangerous to the human psyche...in fact, I know they are.

However, the act of taking drugs can be a pathway to the exploration of your spiritual self, so in that sense, to some people, it may be a necessary experience if that is a path they wish to take.

In a sense though, I do not think drugs HAVE positively influenced a generation of kids as a large percentage of these kids fall into bad habits and it truly can be a LONG ROAD back from there.

Also, some spiritual lore says that the use of illegal drugs can raise the power of the KUNDALINI which is dormant in the location of the ROOT CHAKRA. Involuntary raising of the Kundalini such as that through the use of drugs, can lead to insanity and other serious mental problems. It can make the path harder as clarity is lost and confusion reigns.
