In my observations mdma is roughly twice as potent.
I think the effects argument is way too subjective though.
What I was really hoping is that one of our chemist friends here could make an argument against structural similarity. In the case I posted they make good arguments with regards to GHB and 1,4 - Butanediol. They mention polarity and the way the molecule folds in 3d as well as.
"Each of the three experts agreed that the two substances in question contain a different "functional group": 1,4-butanediol has an alcohol major functional group while GHB has a carboxylic acid major functional group. That is, one is commonly classified as an alcohol or diol, and one is an acid. Those functional groups impart [*5] physical properties to the chemicals, such as acidity levels, melting and boiling points, and odors. All three also agreed that 1,4-butanediol can be converted into GHB within the human body upon ingestion.
Both of the defendants' experts concluded that 1,4-butanediol and GHB are not substantially similar in chemical structure, and that the majority of experts in their field would agree with them. Both based their conclusions upon a number of criteria, including the fact that GHB is an acid and 1,4-butanediol is generally classified as an alcohol. They testified that the two substances would be classified in different parts of an organic chemistry book, which is organized by functional group, and that a student who stated on a college exam that GHB and 1,4-butanediol were similar in chemical structure would indeed fail such an exam.
Dr. Haley related that GHB has a negative charge at one end of its structure, and a positive charge at the other, so that the ends necessarily attract, thereby effectively rendering GHB an unstable molecule. In contrast, 1,4-butanediol does not have such properties and would remain linear. Likewise, Dr. Schuster stated that when illustrated three dimensionally, [*6] GHB folded over upon itself, and would not appear static because of its instability.
Both experts testified that results from a nuclear magnetic resonance (NMR) spectometer, routinely used by chemists to analyze the nature of the functional groups present, documents the structural dissimilarity of 1,4-butanediol and GHB.
The Government's witness, a DEA employee with a degree in polymer (rather than organic) chemistry, disputed the conclusions drawn by Dr. Haley and Dr. Schuster that the two chemicals were not structurally similar. Dr. DiBernardino's principal disagreement was the importance placed on the functional group in assessing chemical structure. He testified that while comparing functional groups might illustrate different properties and reactivity of the chemical substances, such comparisons were not relevant in determining structural differences."
