My younger borther has struggled his whole life, when he was younger, man did he love to eat! He was chubby at first but enjoyed working out a lot too so never really struggled with weight. But now, i've seen it for years, first around alcohol: he could go without drink for weeks but when he did, he wouldn't stop until he at least got really, really drunk, even at weddings and family dos. E-cigs, can smoke a cartridge in a day even if he doesn't particularly like it. And now it's the same situation with weed.
If he gets a bag he will not stop until it's all gone. And apparently weed being non-toxic means it's ok to go completely nuts.
Do some otherwise intelligent folk not know when to stop? And is it genetic? I admit do enjoy the occasional drink, but only if i'm with my gf or other social environment. But i've never felt the need to go over board like this and I would say i've more to stress about than him.
I'm worried because i'm supposed to be looking after him (our parents are abroad) and now he talks about how cool psychedelics are which got me concerned.
Does he actually need help of some kind? He doesn't seems emotionally distressed in anyway?
