1. In the early 1900’s the Mexicans migrated to America and they brought their language, customs, and traditions and that includes the use of marijuana.

3. Cannabis was demonized the same way the Mexicans were. It became an excuse to deport Mexicans.
4. For 59 years until 1996 when California acknowledged the benefits of marijuana, it was considered with no medical value.
