Welcome! There are so many people here that can help you out. Most of us have/had a DOC (drug of choice), but at the same time many of us have experience with a multitude of substances.
This is is a culture and to the uninitiated it can appear daunting and exclusive. There's a lot of slang and jargon involved in this world, so do not be afraid to ask for clarification on anything unclear. What is it you're looking to learn about specifically? Someone will be able to point ya in the right direction to get you some answers.
