Iowa’s new medical cannabis law goes into effect on July 1, but “obtaining the medicine will be difficult and manufacturers said it’s unclear if the state’s effort will be viable,” Linley Sanders reported for the Associated Press this week. Her story illuminated a few reasons the law won’t help most of the people who could potentially benefit from access to cannabis derivatives.

Iowa lawmakers closed out the session with all-nighter so as not to adjourn without doing something on this issue. The previous medical cannabis law, adopted in similar last-minute fashion three years earlier, was due to expire this summer. Even for people with seizure disorders, the only conditions for which cannabis oil was allowed, the old law was too limited and unworkable.

As the new law’s defects become more obvious, we need to remember that most state legislators favored a better alternative. House Republicans thwarted their efforts.
