A medical marijuana advocate says patients who get state approval can legally grow their own marijuana.

But Columbia attorney and medical marijuana supporter Dan Viets tells Missourinet that transporting the seeds to Missouri is illegal.

Viets says there’s a lot of interest from pain patients but the growing will be legal.

Thousands of Missourians will be legally using medical marijuana soon, probably by early next year.

Veets is part of a group hosting a seminar for medical marijuana patients and caregivers this Saturday in downtown Columbia.

Last November, Missouri voters approved a Constitutional amendment allowing doctors to recommend medical marijuana to patients with certain illnesses.
