Categories and Examples
1. Psychoactive Substances: These include analogues of tryptamines and phenethylamines, known for their psychoactive effects.
2. Non-Psychoactive Substances: This group includes analogues of controlled anabolic steroids and other performance and image-enhancing drugs (PIEDs), such as nootropics, weight loss drugs, and erectile dysfunction medications.
Challenges and Risks
• Unpredictable Effects: The pharmacological activities of these compounds are not always predictable based on their structure alone. This unpredictability is due to the structure-activity relationship (SAR) paradox, where substances with similar structures can have different effects, and vice versa.
• Naming Confusion: The lack of standardized naming conventions and regional variations can lead to dangerous mix-ups for users.
Designer drugs pose significant challenges due to their evolving nature and the complexities involved in their regulation and identification. This overview highlights the importance of understanding the diverse and unpredictable nature of these substances.
