Always a great visit Darren. Thank guys.





















Thank you all!


I love that Ethos consistently lives up to its values and delivers on its promises. 💯 There are thousands of dispensaries with similar products and prices, but Ethos listens to its customers. It's convenient to know that I don’t have to search through a thousand different dispensaries for what I want on certain days because Ethos often has great deals available. They are very consistent and hold to their commitments.
They proactively inform me and work hard to maximize my discounts—what a treat! 💵 Plus, they offer exclusive deals for medical and adult users, and I admit I sometimes feel a little envious of the fantastic deals available for adult users! 😅 I’m thrilled to give Ethos a five out of five rating! ⭐ With so many options, I wholeheartedly recommend Ethos dispensaries to anyone looking for a top-notch experience! 🌿










The degradation of the loyalty system as a medical patient over the last several years has been a major disappointment. The latest iteration is particularly bad, essentially cutting the value of points in half and drastically raising the thresholds in which you can use them. Business must be doing well and growing quickly enough that it’s resulted in the sharp decline the loyalty program has seen.
Great place to stop in especially if recreational. If you’re a medical patient, your dollar may go farther elsewhere.




























I love them, the service is very good, they always give u the best customer service... They always give u the best product on your money










This essentially means you are not paying the exorbitant Massachusetts marijuana tax.
My only complaint with this destination is they should disc products at 21%, not 20%. This way the discount will be slightly more than eliminating the sales tax and I would recommend this venue even more so than I already do.
I guess my only complaint is, I would like someway to receive further discounts by spreading the good news about this company, online, in person, and whichever other way I can.
I highly recommend they change their policies, so if you write a positive review which is seen by more than 50 people than you will receive a discount on accessories purchases. I believe legally they cannot give discounts or freebies in regards to actual THC products.
I am very familiar with the landscape, in Watertown off the top of my head I know that there is a venue called Bud’s goods, &
AYR dispensary
I can assure you that the prices at ethos are consistently, the same or lower than the competitors in the area. I will advise, checking the discount sections of their competitors however, as occasionally these prices will beat the ones you find at ethos.
That being said, this rarely happens, so, in some respect it is a waste of time to do this. However, if you are looking for a product that is not being discounted based on the day of the week, I would still recommend checking the prices of AR and buds goods
I have no incentive to write this review, but I emphasize that there should be some mechanism which rewards authentic reviews, which highlight the clean, friendly and inexpensive options available at this dispensary


I’ve never had an issue here and would recommend it to any and everyone - anyone saying they’ve had a bad experience I can guarantee is greatly exaggerating. Everyone here is so wonderful and I’ve been there all times of the day and never had an issue.
Truly wonderful - I don’t really go to other dispensaries.



Was a bit strange to have to order on the iPad things in the store.
