This location is easy to find, pleasant to browse and buy in, with knowledgeable and friendly staff. They have a great assortment of products, and a relaxed atmosphere. Their prices are fair, and they run specials often.
INSA is an excellent dispensary that stresses medical uses and works with you to find the strains you need. Though it is one of the newer dispensaries, they have worked hard to become a strong contender in Western Mass.
Excellent chefs make some very high quality concentrates, from wax to crumble, to shatter, and live sugar. Their edibles are high quality, my favorite being the mints(either wintergreen or cinnamon, both are good).
The only down point to this dispensary previously was its bud, but the good people at INSA have put a lot of effort into increasing the quality of their flower - and have, in my opinion. I have tried 4-5 types recently, as their prerolls are a great way to sample the different types. The ones that work best for me are the types mixed with Jack Herer, a famous strain out of the Netherlands. They make great use of this strain, as it’s part of their best flower and concentrates.
I highly recommend INSA for your medical marijuana needs.
