I cannot think of a better way for a kid to find themselves in a difficult situation and do something stupid rather than call for help.
“I’ve been drinking and shouldn’t drive but I can’t call mom for a ride because then she’ll know something is wrong. I’m not that drunk. I’ll make it home fine.”
“Oh no, something was in that pot I smoked and now things are bad. I should go to the hospital but then dad will find out.” (This actually happened to someone in my family decades ago- that the pot they used had been laced with something and they got violently ill. Luckily we’re an open family so off to the hospital they went.)
The kids who are going to drink and whatever are going to do it either way. They’ll just be better about hiding it.
