Ooh Dittany I just ready that LWT you linked to and it brought back how much I hated that column. Just appalling. She comes across as a real woman-hater in that piece, and as in every LWT, only concerned for herself and how awful it is for her, with not a thought for what her children might need from their parent.
If JM is the author, which it seems she may well be - I really think the whole drugs aspect of the current debacle is a red herring. Her appalling relationship with her son and his pretty bad behaviour towards her is far more likely a function of her massive narcissism, and the fact that she's brought them up with this enormous burden of emotional blackmail, so that whatever they do meets with her panic, her soul-searching, her tears - instead of an adult, consistent response. I'm not saying bringing up teenagers is easy and I admit I have no experience of doing it, but I do think she sounds like the type of mother to drive any normal teen to distraction, and make normal teen problems far worse.
Re the drugs themselves, I think a saner and calmer attitude could have avoided a whole lot of shit. She is crying "addict", calling the police and tearing her hair out over a cannabis habit? I smoked dope on and off from 16 to 28, and I also tried several other, more hardcore drugs on occasion. I'm not saying it was good, but it sure as hell was normal, and it certainly wasn't a life-ruining disaster. During that time I completed A-levels, did my degree at Oxford, got a great job which I still have, and settled down with the partner I still have. I gave up dope in the end because it wasn't doing much for me and I saw it as a thing for your teens/20s and not something I wanted to be doing when I was settled and starting a family. Around the same time I cut down on drinking as well, just grew up a bit. I know many, many other people who have followed a similar pattern. I know many more who still do drugs in their 30s and 40s.
I don't actually think drugs are a good thing, but they are a very common feature of our society and acting as if someone has gone right off the rails because they smoke dope is just silly, and I'm sure fuelled the fire of this fallout.
