Up to now, 47 countries around the world have legalized marijuana, 15 states in the United States and Washington, D.C. have legalized marijuana for recreational use, and 20 states have legalized marijuana for medical use.
However, the attitude of the United States towards marijuana was not so open from the beginning. Marijuana has also experienced a long road from cracking down on illegal activities to gradually relaxing to partially legalization. According to the 1965 federal marijuana law, smoking marijuana is illegal, and the possession of marijuana will be sentenced to imprisonment. The drug control regulations of 1970 listed marijuana as a first-class drug together with heroin. In recent years, many states in the United States have gradually relaxed the control of marijuana, allowing the possession and use of marijuana for medical purposes, and the real lifting of the ban will begin in early 2020. Colorado and Washington allowed adults over the age of 21 to legally use recreational marijuana at a certain dose. Subsequently, Oregon, Alaska and the capital, the District of Columbia, also passed the marijuana legalization bill.
The legalization process of marijuana in the United States began almost 10 years ago. Up to now, the situation in various states is different. As shown in the figure below, in fact, it is not only legal and illegal, but also divided into legal processes at different levels, including:
Full legalization: this means that the government has abolished all penalties for the possession and use of marijuana products. Only after full legalization can it pave the way for the legal sale and cultivation of marijuana.
Decriminalization: in this case, some states have eliminated the prison penalty caused by possession of marijuana, but there will be other ways with less punishment, such as receiving traffic tickets. Generally, when the quantity held or sold by the parties is within the limit of non criminal crime, they can pass the Customs by paying a fine of several hundred dollars; But in states with heavier penalties, they may still face imprisonment.
Legalization of medical marijuana: in these States, doctors can recommend the use of marijuana products according to the patient's condition, although there is no direct evidence that marijuana can treat other health problems besides relieving pain, nausea and vomiting caused by chemotherapy and spasticity of multiple sclerosis. In some states with very loose restrictions on medical marijuana, marijuana has actually been legalized.
