Scientists who study medical marijuana will soon have access to a wider variety of strains. The National Institute of Drug Abuse (NIDA) — the federal “dealer” that supplies the drug to scientists — has received numerous complaints from researchers that the drug they supply is too weak compared with what’s sold on the streets, legal or otherwise. But the complaints aren’t responsible for the change, Nature reports. NIDA’s willingness to expand the types of plants available to researchers is tied to the fact that legal marijuana is becoming increasingly available.
