It seems like every nation has a vested interest in manufacturing and trafficking "GET-EM HIGH" drugs into the United States. Fentanyl, Meth, Cocaine, Crack. Flakka, Synthetic Cannabinoids, NBOMes (LSD substitute), Synthetic Cathinones (Bath Salts), Methoxetamine and Ketamine, MDMA /Mephedrone, and U-47700 ("Pink").
Yet, American chemists are seemingly unable to develop similar drugs which we can cheaply manufacture and smuggle into countries like Mexico and China. If China and Mexico want to wage war using drugs against us, we can do the same. What's stopping us? They are addicting and killing us. How is it that we can't do the same?
