I was born in the late 50s. In 5/6th grade I was going to California schools. They had cops come in to talk about drugs. They had a briefcase as a prop. They opened it and it was filled with drugs with ID tags on each, so you could learn to recognize them on site. They burned weed so you could smell it.

The shit part of this was in the lecture which told us that people who do drugs damage their DNA and have all kinds of deformed babies: que the videos and still of horrifically deformed babies with arms coming out of their back.
I was scared shitless. Later in 8th grade when I saw my sister and schoolmate smoking a joint, I thought I was watching them give themselves a death sentence.

In the end, the lies didn't work. I am a pothead to this day.
