He is talking about Heroin but what he said really applies to any mind altering agent especially narcotics. What he says from about 5:00 is to the point and should explain things. What he described there is exactly the movie "Limitless".
Who here thinks any of those cats just day one jumped into heroine? What would you say is the % of those we at least have anecdotal stories and evidence like this video they were smoking weed first? Just saying.
One of the most important things Bartz conveys to me is whatever you are trying to do with drugs you can definitely do without. It may take you longer and may require more work but the side affects of time and work aren't exactly all that bad.
