In short
1D-LSD and 1D-AL-LAD are legal in Germany because their chemical structure is not listed in the NpSG (New Psychoactive Substances Act). Only their predecessors 1cP-LSD and 1V-LSD are included in this and are therefore not legal.
Since in Germany it must be stated exactly what is prohibited and 1D-LSD and 1D-AL-LAD are not listed, they are therefore 100% legal.
Full explanation
1D-LSD (1-(1,2-dimethylcyclobutane-1-carbonyl)-lysergic acid diethylamide hemi-L-tartrate) and 1D-AL-LAD are so-called LSD derivatives or are also referred to as "prodrugs". This means that 1D-LSD is a modification of lysergic acid, which occurs naturally in the ergot fungus and is the basic substance of "conventional" LSD (lysergic acid diethylamide).
LSD has been banned in Germany since 1971 under the Narcotics Act. Derivatives of LSD, such as the now banned 1cP-LSD or 1V-LSD, are not covered by the Narcotics Act. These are regulated by the NpSG (New Psychoactive Substances Act). This law defines exactly which substances are banned.
Two factors in the law are particularly crucial for the legality of 1D-LSD and 1D-AL-LAD. These are, firstly, the definition that derivatives with a molecular mass of up to 500u (g/mol) are prohibited and the listing of cycloalkylcarbonyls, which are also prohibited.
1D-LSD circumvents these restrictions through its molecular mass of 508.5u (g/mol), which is achieved by the addition of half a tartaric acid molecule to the chemical structure.
The chemical structure of 1D-LSD also contains cycloalkyldimethylcarbonyl residues, but the NpSG only lists cycloalkylcarbonyls, not cycloalkylcarbonyls with additional substitutions.
Since the NpSG must explicitly state which substitutions are prohibited, 1D-LSD is not covered by the NpSG and is therefore 100% legal in Germany.
If the text of the law changes, this will not happen overnight, but will first have to go through all the legislative bodies. In this case, we would inform you in good time and you would still have enough time for extensive research.
