I was a medical marijuana patient in the Oregon Medical Marijuana Program (OMMP) for five years, but had to let my enrollment lapse once the fees were doubled. Being a medical marijuana patient in Oregon isn’t cheap. First there are costs to visit a primary doctor. Then there are costs associated with the medical marijuana clinic (assuming your primary doctor won’t sign the forms). Then there are fees for applying to the OMMP. When all is said and done it costs hundreds of dollars.
