Presumably, all people who are addicted to drugs are also using them. because they're addicted.

Therefore, drug addiction can double-categorize with drug users.

However, not all drug users are addicts - so they should remain separate categories, and drug users should still be added manually to people who use drugs but aren't addicted.
