Regular Use Long-Term Side Effects

Before we list our research, it’s important to define what long term cannabis use actually is.

Despite lacking a clear-cut definition in scientific literature as for the definition of regular cannabis use, long-term use, frequent use, and chronic use, it is generally characterized by weekly or more frequent THC consumption over extended periods of time.

Mental health and cannabis use are tragically intertwined; twice as many individuals suffering from severe psychological conditions such as schizophrenia, bipolar disorder, depression or anxiety also regularly consume marijuana.
