Terms and Definitions

Marijuana, also known as cannabis, refers to a group of three plants with psychoactive properties, Cannabis sativa, Cannabis indica, and Cannabis ruderalis. The plant's dried leaves, flowers, stems, and seeds are commonly used recreationally for their effects on the mind and body, usually causing a "high." It is also used for medicinal purposes, including pain control.

Legalization is the process of removing legal prohibitions against something, making it legal and permissible under law. In the context of marijuana, it refers to state or federal laws being updated or removed to allow for the legal sale, possession, use, and distribution of marijuana.

Medical marijuana refers to the use of the marijuana plant or its chemicals for the treatment of diseases or conditions. It's the same product as recreational marijuana, but it's taken for medical purposes. It can be prescribed by doctors in states where it's legal and can come in various forms like pills, oils, or edible products.

Recreational marijuana refers to the use of marijuana purely for personal enjoyment rather than for health or medical reasons. More simply, it is marijuana used to induce the "high" sensation, for pleasure, or other forms of entertainment.

Decriminalization is the lessening of criminal penalties despite the act remain illegal. In terms of marijuana decriminalization, it means reducing or removing the penalties for possessing and using marijuana, although selling and distributing it remains illegal.

In the U.S., laws can be enacted by both the federal (national) government and state governments. Federal law applies throughout the country and trumps state law when there's a conflict. State law varies from state to state. In the context of marijuana, while it remains illegal under federal law, many states have passed legislation legalizing its use in various forms.

A psychoactive substance is a chemical that changes brain function and results in alterations in perception, mood, consciousness, cognition, or behavior. Marijuana is considered a psychoactive substance because of its constituent compound, Tetrahydrocannabinol (THC), which has mind-altering effects.
