The only issues I have with your post is that coke is not an opiate (cocaine comes from the Coca plant) and that you should be careful with Ecstasy. After all, ecstasy by definition is MDMA cut with meth. Most of the time you'll never know how much of the relatively harmless MDMA you're getting versus the more harmful methamphetamine, so it's good to be careful lest you develop an addiction.
When did the definition of ecstasy become MDMA cut with meth? I mean, I know people mix stuff in basically to rip off their customers and I'll grant it's been 25 years since I touched the stuff so maybe the language has evolved since *ahem* my day. But having meth in your X never had a nickname other than "getting burned."
I've always thought that MDMA was simply MDMA, but that ecstasy was the pill form which usually got some filler. Since MDMA is a methamphetamine anyways it makes sense to cut the two together.
