To cut a long and painful story short, my eldest grandson is staying with us for a while after yet another falling-out with his mother. He's 19, and frankly immature for his age - he works and earns a decent wage, but seems to have no interests other than going out drinking and playing on his X-Box.
I was cleaning his bedroom today - I know, I know, he's old enough to do it himself, but that's another argument, and one part of the reason he fell out with his mum - and I came across several small clear plastic envelopes, a couple of which had small circles of blue paper in them about the size of my little fingernail, like thin blotting paper.
I'm vaguely familiar with acid tabs, being a child of the 60s, but does anybody have an idea what these things might be? I'd like to have some idea before I confront him. He already has form for drinking to the point of dribbling idiocy - at least, I thought it was the drink, now I'm worried it's something worse.
