Earlier this month on The Tonight Show, Miley Cyrus told host Jimmy Fallon that she’d quit using marijuana because she had a dream “that I would die during my monologue on SNL for some reason, just get so stoned that I just died.”

Almost every media report on marijuana legalization at the state level references the fact that cannabis remains listed as a Schedule I illegal drug in the U.S.

In another words, despite 29 states legalizing medical marijuana and eight states legalizing adult-use marijuana, the United States government still considers marijuana an illegal drug with no health benefits and a high potential for abuse.

But what exactly is a Schedule I illegal drug? Who does the scheduling and why? What are some of the other drugs on the list?

The following answer those questions and provides an overview of the five federal government drug schedules -- including the fact that the U.S. ranks marijuana as having a higher potential for abuse than cocaine, Vicodin and methamphetamines.

You've probably heard this before.

As early as 2008, several reports, including one published in Molecular Pharmaceutics, began proposing various therapeutic pathways by which cannabinoids could treat Alzheimer’s Disease patients, but none were proven.

In 2014, a group of scientists made a breakthrough. The conclusions of their preclinical study were published in the Journal of Alzheimer’s Disease, under the title “The Potential Therapeutic Effects of THC on Alzheimer's Disease."

Speak to the average person about cannabis and they may feel inclined to lower their voice. Perhaps briefly recall memories of wild nights in their college dorm, or never partook, but had friends who did. Some may have particularly strong views on it, based on general beliefs or personal experience.

Who applied to grow medical marijuana in Ohio? The state isn't saying.

After legalizing medical marijuana last year, the state is setting up a massive program to oversee the businesses who grow and sell marijuana as well as doctors who recommend it to patients.

Those who want to grow the drug must apply with the Ohio Department of Commerce, which has already collected applications to be one of Ohio's 12 small-scale medical marijuana farms. But when The Enquirer requested those applications, seeking to report where marijuana growers might be located, the state said it didn't have to share the applications with the public right now. 

A new review conducted by some of the world’s leading experts on cannabis provides 10 tips on how to reduce the potential harm of using cannabis. 

The latest scientific evidence was used to draw up the Lower-Risk Cannabis Use Guidelines (LRCUG) recognising the lack of research-based advice for the millions of people who use cannabis. 

1.  Recognising that there is no such thing as a risk-free drug the guidance suggests avoiding cannabis use as the only way to prevent a risk to health. Although this is logical it is impractical given the millions of people in the United Kingdom who use the drug.

Pennsylvania’s decision last week to award a dozen permits to grow marijuana has ignited a firestorm of controversy, with many losers decrying a lack of transparency and threatening legal action that could delay getting medicine to patients for years.

A newly released survey of nearly 3,000 medical cannabis patients found that nearly all respondents said they could reduce their opioid consumption after adding cannabis to their treatment regimen, and a vast majority preferred cannabis to prescription pills.

In a survey of its patients, the medical cannabis community website HelloMD asked a wide range of questions examining the use of cannabis as a substitute for opioid and non-opioid based pain medication. The study, conducted in cooperation with University of California Berkeley, was led by researchers Amanda Reiman and Mark A. Welty.

Cannabis could be even better at treating migraines than traditionally recommended medications, a new study has found.

Marijuana use is being destigmatized at an unprecedented rate. Between medical marijuana becoming more accepted and several states legalizing the substance during the last election, people are talking openly about cannabis use in a way we have never really seen. And new data about who, exactly, is using the drug might be surprising to some people. It turns out that the modern marijuana user is likely to be a woman — and maybe even a parent.
