Scott Alexander explains how the vastly higher doses taken by recreational drug users compared to psychiatric patients lead to misconceptions about drug safety in clinical settings. Longer summary

Scott Alexander discusses how recreational drug users consume substantially higher doses of drugs compared to psychiatric patients, which leads to misconceptions about drug safety in clinical settings. He provides examples of ketamine and amphetamines to illustrate this point. For ketamine, psychiatric doses are around 280 mg/month, while recreational users consume about 90,000 mg/month. Similarly, for amphetamines, Adderall patients typically take 20 mg daily, whereas methamphetamine addicts use the equivalent of 1000 mg oral amphetamine daily. Scott argues that many concerns about drug side effects in clinical settings are based on studies of recreational users, and that these concerns may not apply to patients taking much lower doses under medical supervision.

Scott Alexander critiques the FDA approval of esketamine for depression, discussing issues with drug development, efficacy, cost, and administration requirements. Longer summary

This post discusses the FDA's approval of esketamine for treatment-resistant depression, highlighting the issues with the pharmaceutical industry's approach to drug development and approval. Scott Alexander explains how companies often make minor changes to existing chemicals to patent them, as in the case of esketamine (a left-handed version of ketamine). He critiques the high cost of esketamine compared to regular ketamine and the FDA's stringent requirements for its administration. The post also questions the efficacy of esketamine based on clinical trials and discusses the inconvenience of the approved delivery method. Scott expresses disappointment that this approval may set a precedent for future psychedelic medicines, making them equally inconvenient and bureaucratic to access. Shorter summary
