If you want to learn a little more about what is going on with him, you can visit the following website:
crackreality.com. it is designed for those who love someone with a coke problem. You will find lots of knowledge and support.
I share this with you because there were a lot of people around me doing coke and crack and it helped me understand and protect myself and my loved ones...
I wish you all the best. If you have any specific questions, feel to email me.
