Perhaps too off topic, but given how easy it is get get opiates from poppy 'milk' - as shown from the original unpublished article - I've wondered why we don't see more of it from fairly tame occasional use like Pollan to addicts going around scoring and milking poppy bulbs in the neighborhood.
Poppies seem to grow really easily in a lot of places. You don't have to be a fancy chemist to just smoke or shoot the gunk.
Here's a typical Vice story on this, big headline, fairly unsatisfying reality lol.
