Dear Dr. H,
Could you advise me on the safest way to cut Heroin? Or
point me to the info on the web?

Hmm... We don't normally come at it from this angle. What kind are you trying to cut? Powder is normally cut with milk sugar or quinine. The idea of "tasting" heroin to determine its purity comes from the days when it was cut with milk sugar. Heroin is bitter is taste. As a result of this, the more bitter the sample, the purer it is; the sweeter it is, less pure. This is one of the reasons for the introduction of quinine as an adulterant: it is bitter in taste, so a sample will be bitter regardless of how much it is cut.
Note: If you cut heroin with quinine, keep the amount low. People can OD on the quinine. There is evidence that perhaps as many as half of what are commonly called "heroin ODs" are really the result of the quinine it is mixed with.
For tar, the adulterants are normally sugar or coffee. Dope that has been excessively cut with sugar is obvious to sight. It takes on a crystalline form. Did you ever make sugar crystals as a kid? It looks the same except for the color.
For the powder there would be nothing to the process, just mix one powder with the other. For the tar, it would be a bit more complex. I don't know how it is done according to Hoyle; as I said, I don't approach this subject from the standpoint of a dealer. What I assume is done is that the dope is dissolved in water, just as a user would do in preparing to inject. Similarly, the sugar or coffee would be dissolved in water--as much as can be put into solution. Then the two solutions would be combined and allowed to evaporate.
I can't image that this information will be used for any purpose I particularly agree with, but I will hope for the best! Best of luck.
