Synthetic cannabis may have been taken off the market, freeing parents from worrying about neighbourhood shops selling addictive drugs.
But for many parents of "tweens" and early teens, the biggest threat to family harmony is elsewhere - in the dozens of media including games, apps and social platforms that keep their children glued to screens of all sizes.
That view of digital games is irrational and cliched. But for many parents, the addictive behaviour of their kids on Xbox or PlayStation is just plain exasperating.
Parents have been infuriated by their kids' media consumption since the year dot. Yet, anecdotally, parents worry more than ever about their kids' intense engagement with social media and games, and their apparently addictive appeal, which often prompts an ugly reaction when they are told to move on and do something offline.
Some adults are equally obsessed, with Twitter, for example, prompting questions about adult addiction.
