A once-
popular misconception held by anti-marijuana advocates, perpetuated by drug dealers and gangsters lacing selling-marijuana with other, more harmful
drugs to induce physical addiction in their buyers.
Technically an impossibility, as marijuana does not cause fatal, or even considerable damage in the short term (not counting injuries sustained while under the influence).
Commonly used as an often-misinterperated metaphorical arugment that if you have taken enough of a drug to have
gone completely out of your
gord, you've taken a "dose" more of it than you should have.
High-Strung Joe- "Stop smokin' that, dude! You're going to have a marijuana overdose, dude! It happened to
Crazy Collin after he bought from that toothless dude we found in the sewer! Willie? WILLIE!?"
Willie the
Pothead- "I feel sooo relaxed...
Like, duuuude... woww... duuuude...."
A Well-Adjusted Pedestrian- "Willie just collapsed and pissed his pants in public: if you ask me, he's already overdosed. Drag him home so he can sleep it off in peace."
