Yes, but there is limited supply and high demand.
There are 8 medical marijuana dispensaries in the state and over 4000 medical marijuana caregivers.
Recreational/retail marijuana is now legal, but stores haven’t opened for that yet, so the only legal way to get it is to grow your own or have someone gift it to you. You can’t legally buy it. So that opened up a huge grey market where people change for delivery or the container, but give the cannabis away for free.
Retail stores have been delayed, so the grey market will be thriving until they open.
