ß-methylphenylethylamine isn't actually a controlled substance, though, or at least it occupies the same grey area as many other so-called "research chemicals."

ß-methylphenylethylamine isn't actually a controlled substance, though, or at least it occupies the same grey area as many other so-called "research chemicals." It's an open question whether a substance like this falls under the Analog Act or not (which bans chemicals which are "substantially similar" to scheduled illicit drugs, but the language is loose enough that chemists can substitute a molecule or two and argue that it doesn't qualify). I find the whole issue fascinating - it's almost like a new era of alchemy.
