People have a right to be addicted to drugs.
If they aren't causing problems for other people and choose not to quit using, no one has a right to force them to stop using drugs. It is their bodies and their decisions. ONLY IF they are negatively affecting other people can the state or government do anything about it.
Not all addicts are crazies who steal for a fix and are all fucked up. In fact, it's an illusion because the only one's we hear about are those kinds. MANY are contributing citizens who simply have a habit.
The word "addict" is a confusing word. It implies somehow a slave or prisoner to the drug. That is false in most cases. More often than not, a drug user can be physically addicted to a substance but still be in total control of their bodies and their free will. They could quit if they decided to, go through a withdrawal, and be done with it. Many others simply don't want to quit.
Also, for a lot of people, drugs are NECESSARY. Some people suffer from various mental ailments such as depression, anxiety, psychosis, etc. and prescription drugs commonly used for treating these things simply don't work but rather illegal drugs or other types of drugs work better. These people can NOT be functional members of society without the drugs that they self medicate with.
It's a FALLACY to assume that all people are the same and no one needs drugs to live a happy life.
Keep Big Brother out of the people's lives.
