First off. My son has been spiraling out of control for the last year. he is a month away from 18. When he doesn't get his way he calls his grandparents and they give into him. I have asked many times not to do this. Long story short. He was staying at their house when this happened... Until 3 weld ago I had never even heard of this stuff. I got a call telling me I had to go to the ER because my kid smoked this stuff. I was asked if I wanted to do a tox screen so I said yes. They asked what I wanted to do so I suggested we wait for the results. They were negative for narcotics so they couldn't keep him as I was going to report him. since then the grsndparents said he can't stay at their house, which I had been trying to get him to come home since he went there in February. He now has been home since going to the hospital but now instead of running away to the grandparents house they just pick him up and drop him off in the city and give him money and he buys this stuff. I'm the one who has to go pick him up at all hours of the night finding him passed out on the curb from smoking this stuff. He is also doing it at home. I don't want him going to the city to buy this stuff but he always finds a ride, and money. I stopped giving him money weeks ago. I want to get him help but I was told that because this stuff is "legal" that nothing can be dine. I'm afraid that when he turns 18 I am going to tell him he has to leave. I am open to any suggestions. I've researched and found this stuff has very severe side effects and I don't know how to help him stop.
