Earlier quoted context omitted.
You'd need a prescription to get it. And I don't believe it's legal for a person with the prescription to sell or give prescribed medicine to other other people.
Hire a researcher with toxoplasmosis ;)
Of course the real problem here is the subversion of the controlled-distribution mechanism to serve a private rather than a public end, a tragedy of the regulatory commons if you like. The basic idea here is good; you don't want drugs like thalidomide being freely prescribed because if they find their way to a pregnant woman consumption is likely to result in horrific birth deformities. This is an abstraction to many Americans because the FDA restricted Thalidomide early, but growing up in Europe I became aware of it from quite a young age because there was a small-but-distinct demographic cohort of people with characteristic deformities.
But what's happening here is the drug manufacturer falsely claiming that there's a serious public health risk in order to get into the controlled-distribution system, and then using that to prevent any potential competitors from entering the market. I imagine that if the FDA had declined to make any of these drugs controlled-distribution then the strategic response would have been to hire a PR firm to plant stories about how the FDA doesn't care about medical vulnerabilities.
