## Core Idea Society’s yes/no on substances tracks **moral fashion and social proof** more than sober harm/benefit math. That gap is exploitable — and dangerous — for anyone who outsources judgment to legality or “what everyone does.” ## Two Arcs **Cigarettes:** US adult use rose to ~4,500/year by the early 1960s, then fell below ~1,500 by the early 2010s. Knowledge of harm mattered; so did smoking becoming *unfashionable*. Marlboro Man imagery → deathbed warnings (e.g. Wayne McLaren) is the culture arc in one lifetime. **Soda vs restricted stimulants:** Soft drinks stayed fully legal and heavily marketed despite population metabolic harm. Compounds like ephedrine (old ethnobotanical lineage, studied metabolic effect, real risk surface) hit control regimes after scare cycles. Legal ≠ safe; restricted ≠ useless. ## Why Disconnect Persists - Copy-the-flock defaults beat personal risk math - Regulatory inertia protects incumbents with “social renown” (caffeine, soda) - Marketing budget normalizes some products; others only appear in “scary” frames - Supermarket SKU explosion (Consumer Reports: ~9k → ~47k products 1975–2008) floods the aisle with legal junk ## Operating Rule Separate **legal / normal / marketed** from **mechanism / dose / evidence**. Ask: actual biochemistry? real harm-benefit? who profits from my adoption? would I still do this without the crowd? what will look barbaric in 30 years? *Source: [[The Biochemical Lever]] — moral fashions / soda vs ephedrine / cigarette series*
