The Colorado Department of Public Health and Environment's Good to Know Colorado campaign endeavors to educate folks about the effects of marijuana — though the focus is typically on its dangers.

For instance, Good to Know's latest effort sketches out the risks of cannabis use by pregnant and breastfeeding women.

But the CDPHE-blessed item that recently caught our eye appears under the umbrella category "Marijuana 101" — specifically, the slang terms for marijuana that parents should know before talking with their kids.

The site lists seventeen nicknames for cannabis — many in common usage, some seriously out of date, and others that are apt to make the average teen burst into laughter upon hearing his/her folks say them during a serious sit-down about the demon plant.

See the seventeen terms below, illustrated with photos largely drawn from our 2009 "Marijuana Porn" slide show.

Number 1: Weed

Number 2: Pot

Number 3: Ganja

Number 4: Bud

Number 5: MJ

Number 6: Keef

Number 7: Boom
