A budtender is the the second person customers and patients see when they enter a medical or recreational marijuana dispensary. Budtenders are like bartenders because they help customers pick out concentrates and edibles, and then prepares their purchases.
Most budtenders are knowledgeable of the available strains and their effects. They provide advice on what to buy based on your preferences.
Budtenders are not always knowledgeable marijuana connoisseurs. Furthermore, budtenders will market overstocked marijuana strains. This does not apply to all dispensaries, but make sure to take a look at other strains available to make sure you are getting the best product.
