(Have name-changed here)
I used to smoke cannabis a bit, and have tried various other drugs on odd occasions (speed, Es, coke, mushrooms) - all before I had children. None of it ever caused me any real problems but I did see other people for whom it did.
I have a very open relationship with my DC and talk freely about most things. They're 10 and 14 and at the moment can't imagine why anyone would ever want to do something as dumb as taking drugs (or drinking alcohol for that matter), which is fine, as it's not yet occurred to them to even ask whether I ever have. But as they get into their teens things will change and they probably will start to ask.
If I tell them the truth I worry that they'd see anything I'd done as OK, almost as a starting point of what's normal, which I'd much rather they didn't. But I hate the thought of lying.
How do you get round this?
