In the past we have had a policy that anyone drinking at play events should simply not play. Everyone did a great job of self policing and it worked well for a smaller group. Now that we have more people, it has gotten more complicated. We have decided that it is better to adopt a policy that does not allow any alcohol consumption at or before play events. For social events, it is still up to the host whether to allow it, so in most cases alcohol will still be welcome at BBQ's, dinners, movie nights, and other social stuff.
