Welcome! I'm sorry the others tended to crap in your thread, it's not what is expected. Instead, you are supposed to get a welcoming e-hug and a little guidance on how we operate and what other forums may be worth checking out based on what info you've provided about yourself. Based on what you said, it sounds like Basic Drug Discussion (BDD) and Other Drugs (OD) would have your meth topics, but weed has enough loyal users that we actually gave them their own Cannabis Discussion (CD). If the later ones on your list regain some of your interest, we also offer a Psychedelics Discussion (PD) and Trip Reports (TR) forums. Of course, we also have more regional discussions, so there is a North and South American Drug Discussion kinda like a social area for Americans, though we also dominate The Lounge (TL) for off-topic social banter. Be warned, TL gets a bit rough at times, something like the shit talking others poured into this thread.
We're happy you've joined us, and look forward to having you in our various discussions.
Out of curiosity - how did you find us, and what convinced you to join up?
