Are designer drugs possible?

are they already there? pass an example in that skin.
are drugs only roughly proteins or is there something more to it? Yes, nearby are designer drugs available already. Designer drugs are synthetic versions of banned drugs created in underground labs. However, they are regularly more dangerous than the actual version of the illegal drugs because they haven't be tested, and they are thus tested on drug addicts.
Early designer drugs included substitutes for heroin, amphetamines, and hallucinogens — including the designer hallucinogen MDMA (ecstacy), and its chemical cousins. There are high-ranking incentives for creating the drugs, as they are illegal and can be sold for lots of money.
The solid defintion of a drug is a non-food chemical/substance from outside of the body that affects the body, specifically the central agitated system, and causes change in behavior. Thus, drugs aren't merely about proteins. They are around how certain chemicals affect the body.
what?! that is to say the dumbest thing ive ever hear
So called "Designer drugs" already exist - they are chemical compounds similar to controlled substance drugs, but near a slightly different molecular structure to avoid being categorized as a restricted substance. An example is alpha-methyfentanyl (China White), which be an unclassified variant of fentanyl, which be a controlled substance.
There is far more to drugs than simply protein - pharmacology is a field of science dyed-in-the-wool to the study of how chemicals (drugs) interact with living organisms.
