About one year ago, I realized my son was smoking weed, my husband and I talked with him and he was very confident that he was doing the right thing, that weed is not harmful, that he was not smoking everyday, that before started he had been getting information on the internet etc etc. Well, I told him that I don't approve of drugs, and I did not want drugs in my house and he would have to stop. A few weeks later I started to realize that the wine and other liquors that we had was getting low. One day he forgot his facebook open, and I have no shame to say that I read it, and I realized that he was smoking and drinking at the same time "that he could higher faster". This time I really confronted him and we had a big fight. But he said he was depressed (but I don't why). Later I read again in facebook page that during a sleepover in his friend house they took a lot of of cold medicine pills. Of course during this period some of his privileges were taken away. This week he left his facebook opened again and he was planning to go to a friend's house to smoke because his parents were away. He said something about "vaping", I don't even know what that means. He was always one of the first in his classes, had good grades, but this year his grades were lower than ever. So it is affecting him but he deny it saying that he is just finding school boring. I don't know What else to do, My husband and I work all day, Now is vacation, any of his friends can come home and give him the drugs, even during school year he was getting the drugs there. Please I need advice, I don't know how to talk with him anymore.
