Why do crazy people take drugs when they're already crazy and not so lucid?

Ugh.

There's no such thing as crazy. There are mental health disorders, among which is addiction.

While most attics have another diagnosis, rarely is it a severe mental illness that would make them not lucid and crazy.

The demographic that most uses drugs are youth, 18 to 20. They're barely even old enough to have been psychologically diagnosed with anything.

They're crazy so they don't have the best judgement. Kind of like how some drunk people have impaired judgement and start driving.

This is a crazy post. You may have all the answers about the crazy.
