I'm not going to defend obnoxious yuppies, but like most problems blamed on drugs, this actually appears to be because they are illegal. If drugs were legal the people growing them would be called farmers, you wouldn't need to raze rainforests to grow them and you could build modern processing plants that recycled the solvents used.

Think carefully every time a story like this comes up, would the problem be solvable if we weren't engaged in this ridiculous, destructive, unwinnable war on drugs?
