Final answer:
The legalization of weed is uncertain, with states moving towards legalization but facing hurdles due to federal restrictions and the need for more research on its benefits and side effects.
Step-by-step explanation:
The question of whether weed will be legalized everywhere is complex and cannot be answered definitively. The current trend shows a substantial shift in public opinion and state laws towards legalization. For instance, since the voters approved it in Colorado in 2012, 42 states and the District of Columbia have passed laws to legalize the use of marijuana to various extents.
Medical research has indicated potential health benefits of marijuana, such as the management of chronic pain, reduction of inflammation, and alleviation of symptoms related to various medical conditions. The FDA, however, has not recognized the marijuana plant as a medicine, in part due to restrictions hampering large-scale studies.
Side effects of marijuana can include altered judgment and coordination, dependency, lung issues, and impaired memory. Uncertainty remains because more extensive, controlled research is needed to fully understand the medicinal and long-term effects of marijuana use. Given the evolving landscape of public opinion, state laws, and scientific research, the answer to whether weed will be legalized globally remains uncertain.
