[nbirqgpp] License for recreational drugs

One can legalize yet still control recreational drugs by requiring users and sellers to be licensed. A different license for each drug. Licenses are the way we deal with other things in society where the licensee has potential to harm others or society. Getting a license may require passing an examination demonstrating that the user is knowledgeable about the drug's effects, interaction with other medicinal and recreational drugs, treatments for addiction. It may require a fee which is kind of a down payment against the harm users of this drug are probabilistically expected to cause society. For addictive drugs, one may be required to prove you belong to a support network who are willing and capable (and perhaps even legally required) of providing support, care, and treatment in the event of addiction. The names and sworn statements of the support network are kept on file.
