Step-by-step explanation:
Mind-Altering Ingredient in Marijuana
The psychoactive ingredient in marijuana that is known for its mind-altering effects is called Tetrahydrocannabinol (THC). THC is responsible for impacting memory, coordination, and can play a role in addiction. Marijuana is a mixture of dried plant parts and contains various chemicals that act on the brain, modifying mood and consciousness. While it has recreational uses, leading to a "high," it can also have long-term effects on brain development, respiratory issues if smoked, and potential problems with child development if used during pregnancy.
THC, along with CBD (cannabidiol), is among the cannabinoids of medical interest. These compounds have led to the FDA approval of certain drugs containing THC for treating nausea from chemotherapy and AIDS-related weight loss issues. CBD is utilized in a medication for severe childhood epilepsy. The effects of psychoactive drugs on the brain include alterations in mood, perception, and behavior, which can lead to addiction.
Marijuana's legal status varies by jurisdiction, and it can be used medicinally or recreationally where permitted. Recreational use of psychoactive substances is typically to produce euphoria, but long-term health implications and legal issues should be considered.
