If a cadet is bringing illegal substances to a CAP activity or arriving high / drunk, then their commander will follow their training and perform the necessary administrative procedures to 1) control the incident and 2) discipline the cadet. This shouldn't be something other officers (nor especially other cadets) should worry about--leave this to the commander. They will know what to do.Preferably, the commander should work with the cadet on rehabilitation and not immediately go nuclear with a 2-B. Teenagers, even cadets, make mistakes--it's part of growing up. A loss of rank, position, or other such treatment may be necessary to reinforce the seriousness of the situation, but there should always be a way for the cadet to redeem themselves unless the first offense was so extreme that they're needed to be removed permanently from CAP. The commander should know what is appropriate.However, this will almost never occur. Most of the cadets that I've dealt or head of with substance abuse issues typically keep their personal and CAP lives separate. If you're just hearing rumors about a cadet's life outside CAP, then you should leave them alone. Let them know they have a place to chat with someone such as a Chaplain, or if you can help them find a medical physician / medical organization that specializes in teenage issues / substance abuse. However, at the end of the day, as long as it's not affecting them or others in CAP then I would not worry about it.CAP officers are not trained on how to handle substance abuse. This is a medical issue for licensed physicians. Don't play a hero; just be understanding and try to direct the cadet to get the help they need. Let the commander do their job on discipline and let the medical physicians do their job on rehabilitation. This isn't something to worry yourself about.Summary: it's highly unlikely this will ever happen near you. If it does, inform their commander and then leave it alone. Also, mass media thrives on fear.
