It's also incredibly easy to grow your own. It's called "weed" for a reason; if you threw some seeds in your back garden, in a few months you'd end up with something that would get you high for almost zero effort.

And if you grow your own, you end up with plenty of "trim" (plant parts that aren't suited for smoking but still have lots of psychoactive ingredients). Most home growers will cook their trim with butter for a few hours, strain off the plant material, and use that to make edibles. It's not as scientific or consistent as the commercial methods, but it's easy and completely safe.
