Lots have been said about research chemicals from legal standards passed in the legislative chambers of countries where research chemicals are sold. Research chemicals are used in the development of novel pharmacotherapies in scientific and medical research. The question of whether research chemicals are approved pose a rather worry state of mind.
If they are not approved why use them for research purpose? And if they are used for research, it means they have been approved for that purpose only and nothing more. Remember research chemicals are not for human consumption but for carrying out research work on in vivo (living organisms). Also used for therapeutic value and toxicology testing.
The ambiguity about whether research chemicals are approved comes from the fact that some countries do not approve the sale of research chemicals by legal standards due to it being subjected to abuse by some persons and this has negative effect on such persons, for example Cannabinoids. Countries where research chemicals are approved and sold have stringent laws on possible abuse and restrictions on some perceived research chemicals that could be abuse not to be sold thereby banning them from the market place. Other than this, research chemicals are approved strictly for research work depending on the geographical location since not every country is in support of research chemicals based on its abuse and smokey chem shop vendor in the UK deals only on approved research chemicals
