Cannabis laws refer to the regulations governing the use, sale, and possession of cannabis, also known as marijuana. These laws vary widely across different regions, with some places allowing recreational and medicinal use, while others maintain strict prohibitions. In many areas, individuals may be allowed to possess a certain amount of cannabis for personal use, but selling it often requires a license. In recent years, several countries and states have reformed their cannabis laws to decriminalize or legalize its use. This shift is often driven by changing public attitudes, potential tax revenue, and the recognition of cannabis for medicinal purposes. However, legal complexities remain, as federal laws may still conflict with state regulations.
