Ladies and Gentlemen of the community - I just found out that kids at LF are using Niacin (perfectly legal in the vitamin section of your local stores) to flush drugs from their system. Read up on the web as the symtoms are easily recognized due to an adverse reaction to nicotinic acid.
Don't think that I am passing along a secret as all the kids seem to know and figure we are stupid. If the doctor didn't prescribe it, there is no reason for kids to have it in their posession. Also look out for requests for cranberry and grap fruit juice as these are diuretics and do the same thing.
Sorry for the bad news, but our babies aren't babies anymore, and the world is just getting too small.
