The U.S. Drug Enforcement Administration (DEA) wants federally-licensed researchers to grow 443,680 grams of cannabis for scientific studies in 2018.

The government-cultivated proposed cannabis, that amounts to a little more than 978 pounds, is slightly less compared to this year’s level. According to the DEA, the 2018 aggregate production quotas will “provide for the estimated medical, scientific, research [and] industrial needs of the United States, lawful export requirements, and the establishment and maintenance of reserve stocks.”

The DEA will also allow the production of 384,460 grams of tetrahydrocannabinols (THC) in 2018.

The Federal Register filing was signed by Acting DEA Administrator Robert W. Patterson, and it established the initial 2018 aggregate production quotas for controlled substances in schedules I and II of the Controlled Substances Act.

The order also allocates quotas of 92,120 grams of cocaine, 40 grams of LSD, 45 grams of heroin, 30 grams of psilocybin, 30 grams of ibogaine and varying levels of many other substances.

This year’s drug production quotas set a limit of 472,000 grams of cannabis and 409,000 grams of THC, which is a higher amount compared to next year’s proposal. To be able to pursue further medical research, the DEA would have to allow for an increased supply of cannabis.
