  10. History of drug use and abuse in the U.S. • Before the 1800s, drug use was generally unregulated • Patent medicines

  11. Early Use of Opiates in the U.S. • Dover’s Powder (Thomas Dover) -introduced to U.S. in 1709. • For treatment of disease • Started a trend?..many other patent medicines were marketed • Widely available at grocery stores, by mail etc..as well as by physicians prescription.

Mostly used for its’ material properties. • 1800s- Physicians used Extracts of the Sativa plant as an all purpose medicine. • Recreational use appears to have developed only much later (1920’s) probably as a reaction to prohibition of alcohol. • Minor use in the 1930s-1950s until demonizing propaganda in the 50s and 60’s produced an unintended soar in popularity of its’ nonmedical use

  18. Patent medicines-heroin

  19. ??

  20. Problems with Patent medicines • They were not patented..contents were not described but were considered proprietary information • Increasing concerns about Addictions and side-effects.

  25. Was Prohibition Successful? Perhaps initially, but the effect was short lived. Other problems also emerged.

  26. An interesting parallel

  27. Clear drop in number of cirrhosis deaths during prohibition

  28. Change in consumption of distilled liquor There was a shift from beer to hard liquors.

  29. Effectiveness of “Prohibition?” Prohibition is a likely factor in the increased crime of this era.

  30. commercial trade in marijuana for recreational use sprang up • New York City, where marijuana "tea pads" were established about 1920. They resembled opium dens or speakeasies except that prices were very low; a man could get high for a quarter

  31. The Evolution of Drug Laws • 1906 Pure Food and Drug Act • 1914 Harrison Act • 1920 Prohibition Amendment • Prohibition repealed by the 21st amendment in 1933

  32. The Evolution of Drug Laws • 1906 Pure Food and Drug Act • 1914 Harrison Act • 1920 Prohibition Amendment • 1937 Marijuana Tax Act

  33. In 1926 the  New Orleans Item and  Morning Tribune, two newspapers under common ownership, published highly sensational exposés of the "menace" of marijuana. 2 They reported that it was coming into New Orleans from Havana, Tampico, and Vera Cruz in large quantities, plus smaller amounts from Texas. • Mr. Eugene Stanley, at that time District Attorney, declared that many of the crimes in New Orleans and the South were thus committed by criminals who relied on the drug to give them a false courage and freedom from restraint. Dr. George Roeling, Coroner, reported that of 450 prisoners investigated, 125 were confirmed users of marihuana. Mr. W. B. Graham, State Narcotic Officer, declared in 1936 that 60 percent of the crimes committed in New Orleans were by marihuana users." 9
