I do not know if you are aware that this statement is a lie. It is a lie which is constantly being spread by Libertarians. It is a particularly insidious lie because it has a large component of truth as it's essential ingredient.
Yes, it is true that for the first hundred and thirty years of this nation's existence, there were no drug laws, but that is exceedingly misleading, because it leaves a deliberately false understanding of the history.
There were no drug laws, because there were no drug problems, because their was d@mned little drug usage. There was little usage because their was little supply or familiarity with Cocainoids and Opiates among the population, and what people there were who were familiar with the opiates regarded them as "medicine."
This all changed after the Civil War when thousands of soldiers became addicted to both cocainoid and opiate pain killers as a result of their injuries. It is reported that 400,000 soldiers on both sides developed what was called "the Soldier's disease."
Add to that, the fact that Cocaine Cola became a very popular and fast growing beverage product, and you can see how things were coming into a confrontation with public policy and the law.
Public Health officials started looking at Patent Medicines in the 1890s, and by the 1900s they realized that something was seriously wrong. Too many people were overdosing on drugs and others were becoming hopelessly addicted to them. By 1906, they pushed for the passage of the "Pure food and drug act" which required manufactures to label what was in their product. It turned out that it was a lot of Alcohol, Cocaine, Marijuana, and Opium.
By 1914, they banned most of this stuff with the Harrison anti-narcotics act.
Drug laws were a response to a societal need to address addiction and death which were the subsequent consequence of the increased popularity of drugs in the latter half of the 19th century. Laws weren't needed prior to this time because drugs were not widely available or widely addicted in the populace at the time.
As usage and addiction grew, laws came about to counteract this destructive trend.
