Governor Dayton signs legislation that makes Minnesota the 22nd state to legalize medicinal marijuana. Minnesotans who are sick or in serious pain may use marijuana, although they may not smoke it. More specifically, they will still not be allowed to access cannabis in leaf form. The drug will be available by mid-2015 in pill and vapor form, as well as in oil form (which has proven especially successful in treating children with seizures). However, pot advocates say that the best and most beneficial way to consume the drug is in its natural form. Patients worry that by signing up for the medical marijuana program, they could be putting themselves at risk of falling into the grasp of police.
