Exactly. An addition for when that wiki entry has been read:
In some cases, a drug is not originally designed with the purpose to circumvent any law but - such as in the case of Nichols and his work - to develop receptor probes. However for a lot of people a significant reason to get NBOMe compounds is that they can be more easy to find and do not have the legal issues something like LSD has.
Some substances deemed 'research chemicals' may be studied intensively (well at least hypothetically) but as long as the drug is used for the reason I just mentioned, it may still be called a 'research chemical'.
Sometimes the reason to use a drug is different, such as exploring rare new compounds just to see how they differ from other ones like it. Then the experimental nature may warrant the term 'research chemical'.
So the "research" may be a cover for sources to sell drugs, the research is the official intention for providing the drug ("not for human consumption", etc). Some people take this seriously though, and they keep calling sampling the drug research (such as when exploring new compounds like I just mentioned), even though you can forget about any article ever being published for academic peer review.

TS, be careful about relying on a friend to provide you with good LSD. Of course you can trust a friend to some extent, but even if a friend means well it still is not impossible to get something else than LSD. Even if it is LSD, a golden unwritten rule is to always start low with any new batch. I would understand if you choose to skip the test with a reagent, but titrating is always wise. Before seeing how deep you can go, first see what the basic effects are about. Even low doses can be quite a wondrous experience if you are new to it!
Is there anything else you wish from this thread?
