Is cannabis legal?
Although the federal government still prohibits the use, cultivation or sale of cannabis, what is legal actually depends on where you live. As of early 2016, cannabis is legal to some degree in nearly half of U.S. states. However, each state has different restrictions on how cannabis can be used, and even in legal states, it is federally illegal, though the federal government has deferred to the states rights within their borders.
For example, Colorado, Washington and Oregon have legalized cannabis for medical and recreational use.
Other states that have legalized cannabis allow medical use only with a doctors recommendation or prescription, and the patient must register for the states medical program.
And some states and cities have decriminalized cannabis, which means that people who use cannabis pay a fine instead of go to prison. But in those states its still illegal to grow or sell, with prison sentences possible.
Finally, cannabis remains illegal in many states, and users, growers and suppliers can be sent to prison.
Cannabis is illegal in most countries outside of the U.S., although a few have decriminalized use or are in the process of legalizing or decriminalizing cannabis.
