In the US, the war on drugs has been a war on states.
The feds have used every tool at their disposal to try to shut down a movement that has spread across the country for over a decade.
They have cracked down on dispensaries and made it more difficult for patients to get medical cannabis, even as the states have been making it easier for patients and doctors to obtain their own supplies.
But they have failed to curb cannabis, at least for now.
Now, the battle lines are becoming clear: How will the US go about ending the war against drugs, and how will states go about getting their citizens legal access to the drug?
In the US today, cannabis is classified as a Schedule I substance that makes it illegal to possess and use cannabis for recreational purposes.
While most states allow medical marijuana to be used for non-medical purposes, some states have made it illegal for nonmedical purposes as well, which has led to a significant increase in legal marijuana dispensaries and growers.
There are now at least 20 states and the District of Columbia with at least one licensed cannabis dispensary.
States have also enacted medical cannabis bills that have passed the state legislature, and are being considered in other states.
While the legalization movement has been largely a grassroots movement, it has been aided by some very powerful lobbying groups.
Medical cannabis advocates and doctors have been lobbying state legislatures to decriminalize cannabis and to provide the same access to medical cannabis as other drugs.
The movement has also pushed to allow marijuana for PTSD and epilepsy treatment and has supported the legalization of cannabis for cancer research.
The federal government has also supported the movement, with many states enacting anti-drug laws, even if they are less restrictive than those in the US.
In some cases, the federal government is actively encouraging states to legalize cannabis for medical purposes.
States have also seen an increase in the number of medical cannabis dispensaries and cultivators.
In 2015, the number was nearly 400, and in 2016, it was 1,200.
Today, there are more than 15,000 licensed dispensaries in the United States.
In 2016, a Colorado dispensary opened and four states, Oregon, Washington, Nevada and Alaska, are planning to open dispensaries.
Medical marijuana laws are also increasingly being challenged in the courts.
In January, a federal judge in Colorado ruled that a state law prohibiting cannabis cultivation and distribution in certain areas of the state was unconstitutional and had the effect of prohibiting the growing and selling of cannabis to adults, even for medicinal purposes.
A federal appeals court also recently ruled that the medical cannabis law in Washington, DC, violated the US Constitution and the U.S. Constitution’s equal protection clause.
In addition to the legal challenges, there is a growing number of states in the country that are challenging the legality of medical marijuana, including California, Oregon and Alaska.
There is also growing opposition to the war in states like California.
The Trump administration has announced a new executive order that would expand federal jurisdiction over medical cannabis to include states with medical cannabis laws.
But while some states and localities are challenging this executive order, other states have filed lawsuits to block the order.
In California, for example, a judge in 2016 ruled that while medical cannabis patients have a constitutional right to access medical cannabis for their own use, the state cannot prevent people from using it for nonprescription purposes.
