Well one of us has got to be wrong, but I'm not sure it's me? You are not burning Heroin. You are vaporising it. That is the whole point of the foil: it allows you to use controlled, indirect heat so as to not burn it. You wanted citations. Will this do:

The experiment is designed to mimic what happens when H is heated on foil and inhaled through a (cold) tube. A tablet of base heroin was indirectly heated in a crucible to 300 degrees C, the vapour produced being collected in a condenser. The condenser was then washed out and the residue tested. It was found to consist almost entirely of diamorphine base in exactly the same form as that started out with, with a little 6-acetylmorphine ( < 6% ). 85.6% of the diamorphine base started out with was recovered unchanged, either from the condenser or from the non-volatilised residue left in the crucible.
Now where's my fucking Mars bar?![]()
Sorry for winding you up - and well done for the research, I have tried but get distracted and lose the interest. Interesting about 6mam - mexican tar has a very high level of this in fact so high its not true heroin - but gets you royaly fucked stronger than 3mam found in afghani.
