My 16 year old son is addicted to cannabis although if you ask him he says he can stop at anytime if he wanted too .. he is completely ruling my life, he got excluded from school nearly 18monetbs ago and has done nothing since .. we have had to move house out of my home town as he had got drugs from dealer and couldnt pay them which led to me and my daughters lives being threatened ..we are now just settling in a new home but hes started again found new dealers to supply him … throws things when he doesnt get his own way or i refuse to give him money .. smashes my house up .. verbally abuses me .. terrorises me daily .. im at the end of my tether and dont know what to do
