The most lucrative drug for drug dealers is generally considered to be heroin. It is cheap to produce, is often in high demand, and sells for a high price in the streets. It is also relatively easy to package and transport, making it convenient for dealers to sell in various markets. Additionally, heroin users often rely on the drug so they will continue to return to buy more.
