I want to make Laudanum or Opium Tincture. There are dozens of recipes on the Internet but most of these recipes haven been resourced from books that are literally hundreds of years old. I was wondering if there are any modern techniques in producing Opium Tincture. I have access to 10 grams of raw Opium acquired in Thailand last year. It still seems fresh. Does anyone know the ratio values of alcohol/opium to produce a strong but not deadly Tincture? Is Vodka the best solvent or ethyl alcohol?
