Which type of drug dealer typically operates at a street level?

The type of drug dealer that typically operates at a street level is the street dealer. Street dealers are directly involved in the sale of illegal drugs to users, often in open areas or specific locations and usually in smaller quantities. They serve as the final point of sale in the distribution chain, providing immediate access to drugs for consumers.

Street dealers usually do not engage in larger-scale distribution, which is characteristic of wholesalers or distributors who manage larger quantities and supply drugs to other dealers or retailers. Retailers might play a similar role, but they often operate within a more structured business model and may refer to sellers who handle drugs at a slightly higher level than street dealers. The street dealer's direct interaction with consumers at the street level makes this answer the most appropriate choice for the question.
