Opiorphin

Opiates such as morphine and heroin function by binding to and stimulating 'pleasure receptors'. It is for this reason that they are attictive. The body naturally makes a range of 'pleasure' compounds called endorphines. These are released after stimuli such as eating and exercise. Rather than directly stimulating 'pleasure receptors', opiorphin slows the breakdown of naturally produced endorphines. Owing to its mechanism of action, opiorphin is thought to be non addictive.

Opiorphin is estimated to be 6 times as powerful as morphine.
