Soil contamination by heavy metals is a growing environmental challenge, particularly in tropical regions. Phytoremediation emerges as a viable and sustainable alternative to conventional techniques. This literature review analyzes studies published between 2010 and 2024 on the use of industrial hemp (Cannabis sativa L.) in remediating soils contaminated with lead (Pb), cadmium (Cd), and zinc (Zn). The results show that the plant exhibits high efficiency in absorbing and tolerating these metals, especially when associated with management practices such as biochar application, nitrogen fertilization, and successive planting cycles. In tropical soils, its adaptability to water stress, acidity, and low fertility enhances its performance. Beyond ecological effectiveness, hemp has economic value through the production of biomass for construction materials, bioenergy, and biocomposites. However, the absence of specific regulations for its technical cultivation in Brazil and the lack of field studies limit its large-scale implementation. It is concluded that industrial hemp is a strategic tool for environmental recovery projects and circular bioeconomy models. Further applied research and the development of public policies are recommended to enable its safe and sustainable use.
