Cultural significance:
- April 20 (4/20) is widely recognized as a holiday for cannabis culture. The most credible origin of “420” points to a group of students from San Rafael High School in Marin County, California, who used the term as a code for meeting to smoke marijuana at 4:20 p.m. The date has since become an international day for marijuana celebration[3].
