Every month, the number of patients cleared to use medical marijuana increases by about 3 percent in Hawaii.

Since dispensary sales kicked off in August, more than 1,000 new patients have registered. Some of them may just be anticipating buying medical marijuana legally, because dispensaries are only open on Oahu and Maui so far.

One dispensary each on Oahu and Maui began selling cannabis in August. Late September, the state Department of Health approved a second dispensary to open on Maui. In October, another Oahu dispensary opened for business.

The dispensaries’ production centers have the capacity to grow 48,000 plants, according to the health department, but had only produced 16,166 plants, as of late October.
