WTF! HIGHER LEARING! THEY GOT CANNIBUS COLLEGES NOW!

Don't expect to pull an all-nighter at Med Grow Cannabis College. Michigan's first training center for medical marijuana education doesn't ask students for their homework. There are no final exams.

"We're more of a trade school," said Nick Tennant, Med Grow's 24-year-old founder.

As states loosen their medical marijuana laws, institutions such as Med Grow are sprouting up, looking to educate potential caregivers about how to enter the cannabis industry the legal way.

Tennant opened the doors of Med Grow's 4,800-square-foot facility near Detroit in September, about 10 months after voters approved the state's medical marijuana act.

Always wanting to be his own boss, Tennant had dropped out of college to manage valet and auto-detail companies. But when his businesses contracted under the smothering recession, he looked to the medical marijuana industry for his next opportunity, months before the measure was up for public vote.

"We knew the law was going to get passed," he said.

In addition to Michigan, 12 states have legalized medical marijuana use: Alaska, California, Colorado, Hawaii, Maine, Montana, Nevada, New Mexico, Oregon, Rhode Island, Vermont and Washington.
