One of the most astounding things about humans is that we’re capable of change. We can change ourselves to adapt to our environments. We can change other things to suit our environments. Our whole evolutionary history is millions of years of seemingly subtle changes that are really quite profound.

We’re biologically hard-wired for change. We crave change culturally. Unfortunately, this desire for change can lead us down some not-so-helpful paths. Some of these paths can even be destructive.

One of these paths is recreational drug use. It seems that people are always looking for the new way to get high, or the new way to make money off of people looking to get high. New drugs and variations of drugs seem to pop up all of the time for people seeking new experiences and new sources of income.

Pink is one such drug. Known chemically as U-47700, pink is an opioid, which means it’s chemically related to other drugs such as heroin, morphine, opium, fentanyl, and carfentanil. People who use pink use it alone or mixed with other drugs, much like they use drugs like heroin.

While heroin is strong, pink is stronger. People use it in powder, pill, and even mist form. Pink is highly dangerous, imported from overseas, and easy to buy online. Only four U.S. states have banned the drug so far, although the U.S. Drug Enforcement Administration (DEA) wants to classify pink in its Schedule I list of drugs. That list includes drugs that people can easily abuse and serve no medical purpose. Other drugs on this list include heroin, LSD, and ecstasy.

Pink is proof positive that while humans are amazing creatures, their desire for change is not always a good thing. Maybe their efforts to regulate the drug will demonstrate another, more positive type of change.
