I know you're young and all but you really need to learn what you're talking about before you talk about it. Half of everything you say is misinformation, which can unintentionally kill someone who listens to said misinformation.
Dextromethorphan (DXM) is an NMDA antagonist, a dissociative similar to but not quite as good, IMHO, as ketamine. Opioids/opiates do not destroy your body, at least not from the chemicals themselves, they don't even destroy your mind either, but they do cause changes if one becomes dependent, though most of those changes are short-term and not permanent, just takes some time. Other factors caused by drug prohibition and certain ROAs that people use can damage the body, but that can happen with any drugs.
Also, please learn how to spell man, shit your fucking 14 years old. But most of all, KNOW what the fuck you are talking about, and this is just wishful thinking on my part but shit, stop fucking talking DXM DXM DXM DXM DXM in every single one of your posts.
