I urgently need help on a topic of discussion with a close friend, who feels he has been set up by the CPS concerning some residue of a controlled drug.
The CPS are claiming that very small traces of narcotine, monactylmorphine and morphine were found on a surface, and because:
1. monactylmorphine is a breakdown product of diamorphine (heroin),
2. It in turn breaks down into morphine,
3. monactylmorphine is commonly seen along with narcotine in illicit drugs,
4. Diamorphine residue would break down (by itself) into monactylmorphine and morphine, over a period of 10 years or more,
it is a proof that the traces found were once diamorphine (heroin).
What's not clear above is:
a) Would diamorphine really break up over a period of 10 years or more into the chemical residues mentioned above, at its own accord?
b) Are there any other products/substances besides heroin that can leave such a residue over time? (I found out narcotine is sold and used legally in medication)
c) what other prescribed products may contain monactylmorphine - especially in powder form if there are any, as an alternative to heroin being its source?
c) Would narcotine break up into monactylmorphine and morphine over a long period of time?
d) Is there any official research into breaking up of chemicals like heroin over a time period, or a list of such chemicals with their expected life spans? If so where can I get the information from, online?
Any help on the above would be very much appreciated – thanks!
