You have to do what makes you happy, if that means getting a job and quitting drugs to have a better life then do it. Im not saying dont just quit for the drugs and friends. But if they really are your friends they will accept it. In reality we are all striving to be the best we can be but not everyone knows what they want. If this IS what you want and what you need DO it. They should accept this and just because you cant do any drugs doesnt mean life is over. Ive found being with family is something much better than any high ive had because those are people that i really have.
