OK, as an intelligent person reading these posts who has never done this, let me say that I am now more confused than before I began reading it.
What EXACTLY is "chasing the dragon"?
What are the two most accepted ways of smoking tar vs. powderized heroin?
Be specific, use descriptive words - for example, don't type "take some tin foil and wrap it around the pen tube." Instead, use specific lengths, widths, etc. Does it go all the way around the tube to make it's own tube, or does it go mostly around, forming a boatish design?
How EXACTLY is this "boat" made? How long is it? How much tin foil is used? Is it wrinkly? etc.
One person with a really good descriptive post could give an indepth and comprehensive explanation of how to do this without all the wordiness and redundant posts that confuse the issue!
