About Grass Roots Marijuana Shop - Portland (21+)

Sitting in Portland's Oakdale neighborhood at 377 St John Street, this 21+ recreational shop has built a strong following over 418 reviews and a 4.8 overall rating. Doors open at 9 AM and stay open until 9 PM every day, giving early risers and after-work shoppers plenty of room. Budtender Jodi gets named in feedback for warm welcomes, and most regulars praise the speed of service and product variety on display. The shop runs cash-only with an on-site ATM, which is worth noting before you arrive. A few customers have flagged frustrations with cartridge returns and the store's exchange policy, particularly when a rosin cart turns out faulty. Worth asking about return terms at checkout if you are buying concentrates for the first time. Otherwise, this is one of Portland's busier neighborhood dispensaries, balancing accessible pricing with adult-use selection that turns over frequently. Stop in for flower, edibles, or pre-rolls and you will likely find a staffer who knows the menu cold.

  • Warm welcome from Jodi
  • Great, quick service
  • Amazing products on shelf

Customer Reviews

Ian Mellott

Don’t buy carts here. I bought a house rosin cart and it was faulty. Couldn’t get one drag from it. Went to exchange for a new one and they said they couldn’t exchange. Only offer a 30% discount on new one. So for the inconvenience of purchasing an unusable product I’m rewarded with the privilege of having to spend an additional $25 plus atm fee. When I asked what would happen if the new cart Im bought messed up, the budtender replied “then I’m sure we can make something happen.” Ok. This is a horrible policy. Carts mess up all the time. Why would you buy from a store that won’t protect your purchase. Look elsewhere for vape needs. Budtender. was nice though. Update: 02/23 As you can see below Grass Roots reached out. It was a misunderstanding. I’m glad too. Because the rosin carts taste great and are a great price.

I went into the location in south Portland on Maine mall rd tonight to grab some flower. When I entered I asked if they take card's. The lady behind the counter said no but they have an atm. I started to walk over to the atm and the lady instructed me to come pick out what I want first so I know how much to take out. So I walked up to the counter and asked what the cheapest 8th are and she said 25 was the cheapest. I than asked if she had any dime bags and she said yes. I than asked if I could get 2 for 20 because that's all I was going to be able to take out of the atm and she said yes it should come out to just under 20 so I said cool and went and got the money. I walk back up to the counter and she ask which dime bag's did I want I picked out 2 and she brought them to the counter and rang them up. This is where it gets horrible. She says it's going to be 23 something and I said I only took out 20 because you said it would be less than 20. She said well it's not and said I can't take out more money it just cost me 3.95 to take out the 20 I just got and that I wasn't able to take out more because I didn't have the 3.95 to cover another 20. She got extremely rude with me for some reason I believe because she realized she messed up telling me what the price was before I took out the money. I than asked her if she could spot me 3 dollars from her tip jar which was full and I would bring it back. She said I'm not helping you buy your weed with my tip money I worked hard for. I highly doubt selling weed is a hard job but anyways . She than perceed to charge me over 13 for what ended on my scale to be a .8 bud. Her customer service was horrible and for a weed dispensary one would think that it would be more pleasant and helpful to there customers. I wasn't looking for a hand out but I only had 20 to spend and I explained that to her and she said she was only referring to one bag but we had picked out the 2 bag's which she said would come out to under 20 before I went to the atm. That's why I took only 20 out. There really wasn't any reason for her to get rude with me being I'm the customer and I was following what she had said. I really feel like I was miss led and ended up being extremely unsatisfied with the whole transaction therefore I doubt I will revisit that location again.
