Dihydrocodeinone (DHC) is a natural alkaloid found in opium poppies (Papaver somniferum). It is a potent opioid agonist that binds to opioid receptors in the brain and central nervous system. DHC has a slower onset and longer duration of action compared to other opioids, and it may be used as a substitution treatment for opioid addiction. It is also used in the pharmaceutical industry for the synthesis of other opioid derivatives. However, due to its potency and addiction potential, DHC is a controlled substance in many countries and its recreational use is generally discouraged.
