My 17 year old works full time, is on more than minimum wage and brings home a decent amount of money for his age. When he started working last year he was putting half his wage into a savings account towards a car. Over the last few months the balance has gone down to almost nothing. He gets paid weekly and since Thursday has spent at least £150 on "nothing."
Last Saturday night he came home and was barely able to stand. His lips were stained a dark blue and Sunday he couldn't get out of bed. Said he'd been drinking with his girlfriend. He went out again last night and seemed completely out of it when he came home and, again, he's in a state today.
He's very secretive, vague about where he's been when asked and if we give him a lift or collect him it's never to or from someone's house, just the end of a road etc. and mostly in a not so nice part of our small town. We don't like his friends. Last Sunday when he was getting over whatever he'd drunk or taken the night before his phone was off. His "friends" rang my other son and accused the oldest of stealing a phone and if he didn't answer his phone they'd come to the house to sort him out. They've apparently apologised since then and he's back hanging around with them.
He has next to nothing to show for his money. He did start buying clothes regularly but hasn't for a good few months now. My husband is at the end of his tether with him and threatening to throw him out if he doesn't change his behaviour.
Does this sound like he's taking drugs? Is there a drug that leaves a blue stain in the mouth and lips? I don't want to talk about this with friends or family so any advice would be appreciated. Thank you.
