The lede in this Time story says it all:
Sugar poses enough health risks that it should be considered a controlled substance just like alcohol and tobacco, contend a team of researchers from the University of California, San Francisco (UCSF).
That’s not quite what UCSF scientists Robert H. Lustig, Laura A. Schmidt, and Claire D. Brindis say in their breathlessly titled opinion piece “The toxic truth about sugar” published by Nature (only the abstract is officially free, but the article can be found here). Alcohol and tobacco may be highly regulated, but in the US the term “controlled substance” is statutorily reserved for specific drugs.
To be sure, Lustig et al. have far-reaching regulatory ambitions.
