There are cheaper dispensaries, but I find myself coming back to Jar regularly. Great employees and good weed. The carts have a habit of shitting the bed before they are fully out of oil, but Jar is great with owning that and offering replacements :)

The South Portland Jar cannabis company store is hands down the best dispensary in the area! Their customer service is top notch and their quality of cannabis is unmatched! We love these guys and you will too! They have the best daily deals around and will hopefully soon be your favorite dispensary around! 🫶💯🎯

Fantastic collection and the coolest jars! They have everything from flower, carts, jays, edibles, weed infused beverages, and honestly more. You don’t need a medical card, and as long as you’re 21 you’ll be granted entrance. They put your license in a scanner, so don’t bother trying to bring a fake. They do a rewards program, which is exciting. All of their product comes in the coolest little jars! Very friendly staff
