COLUMBUS (AP) — The state Medical Board is accepting new petitions through the end of the year from those seeking to add illnesses as qualifying conditions for physicians to recommend medical marijuana to Ohio patients, cleveland.com reported.

The board continues to take the position that once an illness is added to the list of approved conditions, it can’t be removed, according to board spokeswoman Tessa Pollock. Petitions will be reviewed early next year.

AIDS, Alzheimer’s disease, and Amyotrophic lateral sclerosis, or ALS, are among the 21 current approved illnesses, along with cancer, epilepsy, glaucoma and Parkinson’s disease.

Earlier this year the board rejected petitions seeking to add anxiety and autism spectrum disorders as qualifying conditions.

The board will for the first time open up a public comment period, beginning after its Jan. 8 meeting, said executive director Stephanie Louka. Final decisions on new accepting conditions would come after several months.
