The government currently places marijuana in the same category as heroin and LSD.

The Drug Enforcement Administration says it will make a decision in the coming months that could prove to be a watershed moment for the burgeoning legal marijuana industry.

In a memo to lawmakers this week, the DEA announced plans to decide "in the first half of 2016" whether or not it will reschedule marijuana, according to The Washington Post. Cannabis is now listed under the Controlled Substances Act as a Schedule 1 drug, a categorization it shares with other drugs, such as heroin and LSD, which the U.S. government defines as "the most dangerous drugs" that have "no currently accepted medical use and a high potential for abuse."

Advocates for marijuana legalization have long argued that the drug should be rescheduled, considering marijuana's relative safety when compared to a drug like heroin, which caused roughly 11,000 overdose deaths in 2014, according to the National Institutes of Health. The argument for rescheduling marijuana also revolves largely around the drug's potential for medical use, as 23 states have already legalized medical pot to treat a variety of maladies—from cancer to chronic pain—and U.S. Surgeon General Vivek Murthy even admitted last year that "marijuana can be helpful" for certain medical conditions.
