Well, duh, again. Anyone who has ever had teenagers knows that in certain circumstances, and this is one, they can be hell bent to do exactly what you tell them not to do.
The psychological term for it is “Reactance.”
We all want what we’re told we can’t have.
It’s particularly virulent in teen-agers (speaking as a father of two).
I think the best deterrent for bad behavior are parents. My youngest just graduated from HS. In the past 2 months two guys from his class have been involved in MVA's one is paralyzed and one is dead both involving alcohol. The city and school officials are talking about starting programs to prevent these tragedies. I knew these kids and their home circumstance and I was saddened by what happened but not surprised. These programs make the adults feel good and give kids a chance to get out of class.
I agree. Now, here's the $64,000 question: Why would it be any different with abstenence messages?
