Why Does Long-Term THC Use Pose Risks?

As the popularity of cannabis continues to rise, it is important to examine the potential risks associated with long-term THC use. THC, or tetrahydrocannabinol, is the active compound in marijuana that produces psychoactive effects. While cannabis has been used for medicinal and recreational purposes for centuries, long-term THC use can have both short-term and long-term consequences on physical and mental health. This article explores the various reasons why long-term THC use poses risks and provides valuable insights into this important topic.

The Impact of Long-Term THC Use on Mental Health

Long-term THC use has been linked to various mental health issues, including increased risk of developing psychiatric disorders such as schizophrenia and depression.
