A disease attributed to virus, that is generally caused by smoking weed or marijuanna when one is even slightly ill.

The smoking greatly exascerbates the illness and adds to it's duration. Any smoking before your system is purged, will only strengthen the Hippy Death Plague and worsen your symptoms.
When I was smoking at Purchase, trying to lessen a headache and a slight tickling in the back of my throat, I unwittingly opened the door to the full-blown Hippy Death Plague.

Dude, you shouldn't be smoking if you're sick. Don't you know about the Hippy Death Plague?
