A lot of drug resistance develops by medicine misuse (stopping halfway etc). The amount in the bones hints they took it regularly. The amount in the bones in the kid tell they used it in them too. We don't know how much was for specific treament...maybe they always gave them regular doses, we can't tell but the follow up research should provide some hints on their intake over years.
If it varies a lot it was taken mainly as a cure but if it's steady it was just a part of diet or taken in a regular ritual. It might just be diet. For a long time beer was a relatively safe drink, safer then water in populated areas.
Then again it might have happened , we really can't tell since we have no written sources from them just some mummies.
