Pfff. Try food. People naively say "weed is a gateway to other drugs", meaning cocaine. In practice, the biggest drug it opens the highway to is food.

A stoner would smoke half-a-joint and then easily eat a pound of processed meat, then send a whole bag of chips down the hatch, washing it down with two or three pints of beer, and twenty minutes later will be eating ice cream directly from the bucket.

Food is the worst and most dangerous drug of modern human history. It has killed more animals, insects, and humans than any other drug. Cocaine compared to it is a kindergarten party.
