As more arrive to register their children as medical marijuana patients, they have knitted together a random family here, across the suburbs and foothills of Colorado’s Front Range. They are Muslims and conservative Christians, liberal Democrats and conservative Republicans. Now, they cook dinners and babysit for one another. They meet to compare progress and seizure diaries. They discuss the best ways to feed the oil to their children. They wait, and hope for results that mirror the astonishing successes they have seen in television reports and online videos. “I put what fit in my car and drove out here,” said Marisa Kiser, whose 19 month old son, Ezra, has had seizures since he was 3 days old. The families have hung their hopes on a marijuana oil called Charlotte’s Web, which is made by a medical marijuana dispensary in Colorado Springs. The business, called Indispensary, also sells a variety of highly potent marijuana and edibles. Buyers of the medical marijuana must present certifications from two practicing Colorado doctors.
