It's both more and less than people make it out to be. '420' began its sub-rosa linguistic career in 1971 as a bit of slang casually used by a group of high school kids at San Rafael High School in California. '420' (always pronounced "four-twenty," never "four hundred and twenty") came to be an accepted part of the argot within that group of about a dozen pot smokers, beginning as a reminder of the time they planned to meet to light up,
These days '420' is used as a generic way of declaring one likes to use marijuana or just as a term for the substance itself. Its earliest connotation of having to do with the time a certain group of students congregated to smoke wacky tobaccy is unknown to the overwhelming majority of those who now employ the term.
Here's a short little video on why marijuana is illegal. The answer, of course, is politics.
I'm indirectly responsible for the drug-testing program for one section of my company, and I support the program 100%. If employers don't want to hire people who smoke dope, drink alcohol, cuss, don't love Jesus, or are left-handed, that's nobody's business but their own.
But should any of the above be criminalized, as long as smoking dope, drinking alcohol, cussing, failing to love Jesus, or being left-handed harms no one else?
No. Absolutely not.
Happy 4-20 !
