How do I get the help I need?

I'm addicted to drugs. It's more of a mental addiction rather than a physical addiction, but I'm not sure and I KNOW that I need rehab. Not therapy or counseling or meetings, that **** won't work. I'm 17, my parents know but just don't understand, and I need something to happen today. This is the last straw. I will do anything I can get, but I did quit marijuana. Lately it's been huffing and robotrippin pretty (tussin pills, nyquil, ccc's) etc and as much as I hate it and cry at night, I continue to do so. I can't stop. What are my options? I can drive...
