Nonexistent, except for a comment from my mom once that she didn’t understand why drugs were illegal, didn’t care what people did in their own homes.

With my kids just an open door communication style, they ask I answer - so like when one got a boyfriend and both were first timers, she asked about STI, was it safe if she had birth control, and we talked about the HPV, HIV, Hepatitis, things you could possibly get from being born or nonsexual contact, but also about relative risk, and how there is always going to be some, but that shouldn’t stop you from living, being open and talking with your sex partners. And talked about enthusiasm rather than consent, that you should not push anyone for consent, wait until both of you feel enthusiastic about sex to do it.

Oh and drugs they don’t seem interested in, alcohol I let them try rarely off and on when teenagers and all have turned out to be responsible with it, some drink occasionally, or weekly, some none, but none abuse it - their bio dad was alcoholic/drug abuser as was his dad and brother so they are kinda hyper aware already that they could have a risk, and have them as bad examples. They don’t want a dependency, so all tread lightly. None seem to have inherited the alcoholic/addictive trait though.
