High on the list of what to look out for when purchasing a pre-rolled joint is the producer of the product, some producers are known for their history of producing quality products as opposed to those who sell the bad stuff. The dispensaries and stores also fall under this category as good dispensaries always make sure to confirm that what they sell is of top quality. So when purchasing a pre-rolled joint double check on the dispensary or store to confirm that they have a good history of top quality products.
