In 1944, New York Mayor Fiorello LaGuardia commissioned research to be performed by the New York Academy of Science. Among their conclusions: they found marijuana did not lead to significant addiction in the medical sense of the word. They also did not find any evidence marijuana led to morphine, heroin or cocaine addiction.
We now know that while estimates vary, marijuana leads to dependence in around 9 to 10% of its adult users. By comparison, cocaine, a schedule 2 substance “with less abuse potential than schedule 1 drugs” hooks 20% of those who use it. Around 25% of heroin users become addicted.
The worst is tobacco, where the number is closer to 30% of smokers, many of whom go on to die because of their addiction.
