How Cracking the Code of Party Drugs Dramatically Increased Synthetic Drug Development
Present day, as outlined by The New York Times, drug development is ever evolving. With information, academic and informal, being more available than ever before, it comes as no surprise that it is being used for some bad, such as street drug development. However, the bigger problem at hand is the recent discovery of how older drugs can be used as model systems for illicit drug synthesis, and how a surplus of information is being used by irresponsible chemists to harm society at an unprecedented rate.
Since the 1980s, party drugs such as MDMA, made illegal in the U.S. in 1985, (Figure 1) have been synthesized and consumed for its stimulant and psychedelic effects (NIH).
Figure 1. Chemical structure of MDMA.
Where the problem begins is the discovery of the ease at which alternative drugs with similar effects could be synthesized, a prime example of this being methylone (Figure 2) and its easy addition of oxygen, more specifically a oxygen with 2 bonds to a carbon, known as a ketone.
Figure 2. Chemical structure of methylone.
Methylone was the first largely produced and consumed new-age drug of its class, synthetic cathinones, more commonly known as "bath salts" being legally sold in the U.S. in 2010, and was also the start of using templates for drug development due to the high amount of manipulations that can be made to get desired drug effects such as increasing or decreasing potency, addictiveness, and of course avoiding the law by dodging substance bans. For those more chemically inclined, it can be noted that the transformation to methylone can be done many ways. Commonly, a coupling reaction followed by the oxidation of an added alcohol to the desired ketone (while this information will be shared as its rather basic, most chemical reactions used to achieve the compounds in this blog will not be for obvious reasons).
What exactly is a cathinone? It is a compound that follows the general structure of figure 3. More specifically, it contains a carbon ring (denoted by the the connecting points of the lines, and 3 additionally lines depicting double bonds that make it a benzene ring, the fancy chemical name, in blue), a oxygen atom (yellow), a carbon backbone highlighted in tan, as well as a nitrogen atom shown in green. To obtain the desired characteristics of cathinones, as mentioned earlier, the most relevant groups are the carbon ring, carbon backbone, and nitrogen atom. This is seen in methylone (Figure 2), where an additional ring was added to the carbon ring and a carbon atom was added to the nitrogen.

Figure 4. Structure of dopamine.
The primary difficulty and concern of cathinones is their resemblance to dopamine (Figure 4). Due to this, the brain's ability to regulate dopamine is disrupted and causes a false euphoria that is addicting and dangerous. Due to the side effects of these drugs, high blood pressure, heart attack, and many more acute and chronic issues that result in death or disability can be caused.
Further efforts result in the synthesis of MDPV (Figure 5) which was "too extreme" causing abnormally high amounts of psychosis, the synthesis of ethylone (Figure 6, a much simpler compound due to less abstract additions, and less extreme compound), NEP and eutylone(Figure 7 & 8, used as adulterants in other drugs), as well as NNDP throughout the early 2010s to present day.

Figure 10. Structure of nitazenes, as well as their areas of interest.
By the end of 2024 at least 22 nitazene molecules have been identified. The greatest concern with this class of drug is the cost of production and sale being extremely low, as well as the potency. As reported by NPS Discovery, some nitazenes are reported to be 90 times more potent then fentanyl. For reference, morphine, a commonly used drug in the medical world for pain management, is 100 times less potent than fentanyl. This means some nitazenes are 900 plus times more potent than industry standard pain medication!
Who is making these compounds? Historically, unregulated labs operated by a mix of trained chemists and informally trained individuals in China, India, as well as smaller illicit operations in Mexico are largely responsible. However, it is important to note that the ever changing nature of laws around the synthesis of these drugs has created a need for more diversity in location and scale of operation.
This dire situation in the losing war against drugs begs a few questions to be asked. Should published research be more limited to avoid the public knowledge of drug synthesis techniques? How can one stop a problem so far beyond management on the street level? What awful drug will hit the streets next?
