Mapping NAACR Alcohol and Tobacco use to CDM

Hi @rgand!

These problems are not solved by the external terminologies, so they require an OMOP-made solution, as do many others.
Even though the documentation is not perfect, the smoking status problem was actually solved, so you can find more information here:

The alcohol use problem is far from being solved. You’ll find a constellation of Standard concepts across various vocabularies, semantic flavors, and modeling approaches (pre-coordination vs post-). However, I can’t recommend using any of them. We need to plan another sprint to solve the problem.
