As you have already read the reasons that Wikipedia hotlinks are discouraged please do not just direct people there anyway. Wikipedia is a dynamic resource; the content of the articles you link to may change or even disappear, which would render this thread useless to future readers. If there is content on Wikipedia that is highly relevant to the discussion then please present it in the thread.
Same applies to hotlinking images from other sites. Hotlinks are unstable and go dead with time. If you have images that are relevant to the discussion then please upload them onto Drugs
-Forum either in the Image Gallery
, a personal folder on your profile
page, or as an attachment to your post. Schematics of the structures of these compounds can already be found in their respective drug
info threads, and these can be found using the forum search engine or the research chemical
index stickied at the top of each research chemical sub-forum.
Back on topic: yes, all of the compounds named above are class B controlled substances in the UK under the clause on cathinone derivatives. The clause makes provision for alpha-alkyl chains of varying length.
As for whether any of these substances are a replacement for anything (and God forbid they should be viewed as compounds in their own right rather than as a substitute for X, Y or Z).. time will tell. There is currently very little information regarding human use of these substances out there, so it seems premature to draw any conclusions about their respective merits and detractions.
