isomer refers to optical and geometric isomers not to positional isomers otherwise anything with the same molecular formula would be covered which is not what was intended.
This is also what I thought the original intention was, but the problem is, that it is not clearly defined anywhere (at least not in the german and austrian drug law).
...which is not entirely true! For example does the German BtmG state (more or less) clearly:
Anlage I (for § 1 Para. 1)
Non-Tradeable Narcotics*
- Acetorphin
...
(long list of substances, which ends with)
...
- 2,4,5-Trimethoxyamfetamin
- the esters, ethers and molecular compounds# of all substances mentioned in this list, as far as they are not mentioned in a different 'Anlage' (i.e. schedule list; Note: There are further 2 lists in the German Narcotics Act) and as far as such esters, ethers and molecular compounds# can exist.+
- the salts of all substances mentioned in this list, as far as they can exist.+
[...]
- the stereoisomers of all substances listed in this and any other 'Anlage' if they are intended to be abused as intoxicating agent.
* Note: "Anlage 1" equals more or less Schedule 1 of the US Controlled Substances Act.
# The term 'molecular compound' (translated from the German word "Molekülverbindung") is in my experience a bit unusual in scientific German language. The most common and accepted definition means: Any compound resp. derivative made of covalent bonds. I'm not a lawyer, but I understand this term in the context of this law as 'any covalently formed derivative' (in contrary to any ionic derivative, but these were of course already with the phrase "...any salt..."). This excludes regioisomers, but (theoretically) includes for examples amides, carbamates, cyclic derivates, the famous beta-keto-derivatives and so on; everything that can be formed from a scheduled drug by adding covalent bonds. Sounds at first sight like one of the broadest "analogue laws" worldwide to me if applied literally, but AFAIK is such a broad, literal application of the term
not current practice. No idea what the inventor of this term originally meant though...
So well, apart from that special phrasing, the kind of illegal derivatives are quite unambiguously defined. And fortunately, the phrasing is not nearly as broad as its equivalent in the UK, US or Australian law. The term "isomer" is used
only in the context of
stereoisomer, and even here it applies
only if the respective stereoisomers are intended to be used as recreational drugs. If you for example simply intend to gather a collection of rare compounds without ever aiming at ingesting them, you would be still on the legal side. BUT: Any trace of the forbidden isomer as an impurity present and you are fucked. Also might it get difficult to persuade a judge that this (stereo)isomer in your possession was really not intended for consumption but something totally unrelated. Well, in practice the court has actually to prove
first that you had such an intention and
then you need to demonstrate the opposite, but I'm afraid that any clever prosecutor won't have a big problem with showing this.
It's just this term 'molecular compound' that is causing headaches to me...
And by the way, the phrasing at the end of 'Anlage 2' & '3' is almost identical. At least no further ambiguous phrases!
+ These additional phrases are particularly ridiculous, because they say literally that certain derivatives are prohibited as long as they can exist (the original phrase says "...and as fas as the existence of such esters, ethers and molecular compounds
is possible"). Aaaaah yeah, here we have one unique chance to witness proverbial German correctness: German law does not allow something to be prohibited if it can not exist at all.
