An AP story titled Scientist haunted by misuse of drugs he invented notes that David Nichols is haunted by how humans hijack his work to make street drugs, sometimes causing overdose deaths.

Although the title of the piece speaks of invention, the story itself concerns journal publication [eg, He published his study, found little interest from pharmaceutical companies in his chemical, called MTA, and moved on.]

For the record, Nichols does have patents. For example,
