Away from home and parental supervision, the children get up to all sorts of mischief at university. They learn about their chosen profession, of course, which is why you are spending all that money to educate them, but you know they are learning how to be adults at the same time. It's a transition phase, those four (usually more) years.
If you are so fortunate as to send your child to school in Georgia, the one in the States that is, they will learn how to sneak around to have a smoke. Uncover hidden reaches where they can light up without being caught by authorities. There will be no tobacco products allowed anywhere on any campus in the entire state, which never had much of a tobacco industry anyway so there's no lobbyists to complain.
Your child will not be exposed to second hand smoke in a dormitory room or while walking the leafy environs of the campus. The huddled masses will no longer be allowed to congregate near the entrance of a building, puffing away. But neither will anyone be allowed to use electronic cigarettes, with their harmless water vapor emissions. That's what the kids will learn to smoke without detection. There is no smell to give them away. The vapor released is just water, the sort of thing that would dissipate in the same way the clouds of steam dissipate from the communal showers.
Learning how to skirt laws is an important lesson for the child to master. They'll never get far in this world if they don't.
If smoking is the least of your worries, then steer your offspring to the vast school system in California. At least you know that your daughter won't be sexually assaulted, or your son accused of the same by some girl he hooked up with at a party. No indeed. No sex will take place on a California university campus without the express consent of the parties involved.
Students in California will be trained in the fine art of contract negotiation. Or they'll discover the character-building value of celibacy.
When you were a student, you just didn't really know what consent meant when you found yourself alone with someone you fancied. Women might be worrying about how far is too far and should I let him, while the men were not thinking with their heads at all, beyond a little voice that whispered something about offering encouragement if the lady seemed to waver in her commitment.
As a parent, you won't have to worry about your child going through that same torment. The couple, or however many are involved in sexual activity at any given time, must all agree. There must be a contract so that no one can later go to the authorities and claim sexual assault.
For now, all it takes is a yes. As in, let's fuck, and she says yes, let's. If she's drunk, well, a lad might think he heard a yes so he'll be needing to look for non-verbal clues, like her not resisting. Again, if she's had a big feed of drink, the muscles just don't respond to the brain's call for resisting, so what else can a man do to prove he's been given pre-approval?
There will be a need for contracts which the California university system can post online for easy downloading by students caught up in the flurry of raging hormones and human curiosity. It's just a matter of time until the state takes that next step, now that they've made it a law for all involved parties to express their consent to sexual activity.
The schools will likely be offering a class on how to consent, and what better time to explain the legalese of the new state-mandated sexual activity contract that must be signed and then duly notarized. Sure all that coupling before the law changed was spontaneous, and sure there would be less sex if people actually stopped for a minute to sign a contract and had a chance for their heads to clear. Many a young woman would reconsider in the hard light of sobriety, when she waited for her partner to read the fine print before inking his signature. She'd be thinking about waking up next to the wanker and what kind of good morning would that be?
All the problems of sexual discovery, solved by a law. As Charles Dickens wrote in OLIVER TWIST, "If the law supposes that...The law is a ass ---- a idiot."
