a TIME in the 70's where a group of teens would gather after school got out to smoke marijuana. 4:20 was the perfect time because it was after school, enough time to get the weed and smoke before parents got home. since then april 20th has become a "holiday" in which people celebrate smoking marijuana! also, 420 is NOT a police number and they do NOT say that when they see people doing drugs.
"you wana get high? afterall it is 4/20."

April 20th; A day where actual cannabis-smokers do the ganja. Also the day where a bunch of poseurs claim that they're gonna smoke weed on that day to try to be cool, but really don't.
So, I don't do marijuana on 4/20. Fuckin' sue me.

Supposedly "420" was a code used by the San Rafael police department, however, the department has always denied this. A group known as the "Waldos" claim to have originated 420 in San Rafael in 1971. The group met every day at 4:20 PM after school and eventually began to use 420 as a code for marijuana so they could talk about pot in front of parents and teachers.
Can't wait til 420, I'm going to blaze out of my mind.

Hitler's birthday and the anniversary of Columbine. A lot of people smoke weed on 4/20, which is cool but other than that it doesn't look good on the planets reputation.
I'm gonna go smoke weed now.

4/20 is a very awesome day, as long as you're not a parent who's kid got killed at Columbine.

1. The time to get high as adopted by marijuana culture.
2. A way of mentioning marijuana in the presence of authority figures so as not to get caught.
Perhaps the most compelling source of 4:20 is the time of day an H.P. Lovecraft character cites for having become sober after succumbing to the intoxication of a "mirage-plant":

"I had encountered at least one of those curious mirage-plants about which so many of our men told stories. Anderson had warned me of them, and described their appearance very closely—the shaggy stalk, the spiky leaves, and the mottled blossoms whose gaseous dream-breeding exhalations penetrate every existing make of mask...Although everything was spinning perilously, I tried to start in the right direction and hack my way ahead. My route must have been far from straight, for it seemed hours before I was free of the mirage-plant's pervasive influence. Gradually the dancing lights began to disappear, and the shimmering spectral scenery began to assume the aspect of solidity. When I did get wholly clear I looked at my watch and was astonished to find that the time was only 4:20. Though eternities had seemed to pass, the whole experience could have consumed little more than a half-hour."

4:20 originated in San Rafael. What happened was, a group of guys who went to San Rafael High School in 1971 would smoke weed at the Louis Pasteur statue at San Rafael High School, and every time they did this they would do it at 4:20 PM. They would later come up with the term "Louis 4:20" to use when on the phone around their parents or near authoritative figures. It would later become a world wide phenomenon (how it did is beyond me) were stoners would smoke up on April 20 (4/20) at 4:20 AM/PM (depends on how early you wake up). Lastly, 4:20 is not a police code for pot or any other drug.
"Dude, let's get blazed at 4:20 AM and PM man!"
"Alright man! Wait. How the fuck are we gonna make up that early?"
"Oh shit. Fuck. Uhhhhhhhhhhhh. Shit. Oh! I got it! I'll set an alarm!"
"Dude, that's some fuckin' Einstein shit right there bro!"
