Unique to each opioid is its distinct binding affinity to the various classes of opioid receptors (e.g. the μ, κ, and δ opioid receptors are activated at different magnitudes according to the specific receptor binding affinities of the opioid). For example, the opiate alkaloid morphine exhibits high-affinity binding to the μ-opioid receptor ...
The remaining 30% of opioid receptors are located post-synaptically on dendrites of second-order spinothalamic neurons & interneurons. [36] When an opiate binds as an agonist to the GPCR, there will be a signaling cascade resulting in the inhibition of adenylate cyclase and calcium ion channels with the stimulation of potassium ion channels.
As of 2015, an estimated 17 million people use opiates, of which heroin is the most common, [14] [15] and opioid use resulted in 122,000 deaths; [16] also, as of 2015, the total number of heroin users worldwide is believed to have increased in Africa, the Americas, and Asia since 2000. [17]
Carbonate derivatives of 14β-hydroxycodeine "viz., 14β-hydroxy-6-O-(methoxycarbonyl)codeine, 6-O-methoxycarbonyl-14β-(methoxycarbonyloxy)codeine, and 14β-acetoxy-6-O-methoxy-carbonylcodeine, potential substrates for ring C modification in morphinane (sic) alkaloids, were synthesized for the first time."

The realities of opioid use and opioid use disorder in Latin America may be deceptive if observations are limited to epidemiological findings. In the United Nations Office on Drugs and Crime report, [ 205 ] although South America produced 3% of the world's morphine and heroin and 0.01% of its opium, prevalence of use is uneven.
Estimated over 3.43 million prescription opioid users and 3.42 million prescription stimulant users worldwide. [ 2 ] Prescription drug addiction is the chronic, repeated use of a prescription drug in ways other than prescribed for, including using someone else’s prescription.
