My brother smokes weed for 2 years. At the beginning i really worried about him. I was afraid he could become dependent on weed. He suffered from insomnia and anxiety so we went to a doctor and he advised us to go to a cannabis medical dispensary that we found here

So we went to a dispensary and there were a lot of nice and polite people that explained him everything and helped him. My brother doesn't suffer anymore from insomnia and he has become more communicative and calmful. He says weed really helps him to relax sometimes when he smokes it. I think each of us has to make his own choice. And nobody can prohibit us to smoke weed or not.
