The DEA wants to ban another plant. Researchers say the plan is ‘insane.’

The Drug Enforcement Administration has received a torrent of backlash from patients with chronic pain and former opiate users after announcing plans to ban kratom, a plant gaining popularity across the United States for its opiate-like effects.

Kratom, which originates in Southeast Asia, has become more widespread in the United States in the past decade, fueled by online testimonials from users and a lack of federal regulation. Advocates say the plant — typically crushed and mixed or brewed with water — poses few health risks while helping users relieve severe pain and overcome addictions to powerful prescription painkillers.
