Glossary
Possession
In the context of cannabis laws, "possession" refers to having physical control over cannabis products. Laws often specify the amount one can possess, commonly in terms of weight (e.g., ounces, grams). Penalties for possession can range from fines to imprisonment, depending on jurisdiction and the amount possessed.
Decriminalized
Decriminalization means that possession of a small amount of cannabis for personal use is not a criminal offense, but may still be subject to a fine or other administrative penalties. It's a middle ground between full legalization and criminalization. Decriminalization aims to reduce the social and economic costs of enforcing cannabis prohibition, such as arrests and imprisonment.
