With a deadline looming at the end of this month in the most dramatic federal-state showdown yet in Colorado over marijuana, a state lawmaker has proposed a bill that would raise another cannabis clash. The bill aims to study using the growing of industrial hemp to clean polluted soil, a process known as phytoremediation. There is some evidence that hemp plants can suck toxic substances out of the ground. Growing hemp is illegal under federal law without approval from the Drug Enforcement Administration.
