All accurate, for completion I would also add:

Joints are just weed wrapped in a thin paper, smoked like a cigarette.

Bongs have water which cools the smoke down a bit and allows for bigger hits. You also inhale the smoke straight into your lungs as opposed to pulling it into your mouth and then inhaling like with a joint.

A spliff is a joint mixed with tobacco, gives you more of the tobacco buzz but hits much harsher than a blunt

Edibles can also last a lot longer than smoking (and obviously better for your lungs). Smoking gets everything in your system at once, lasting for up to an hour or two (at least for some people), while edibles start working while they're being digested and continue working for a few hours at least.

In my experience, the high is just slightly different with each method, with the biggest difference being between smoking and eating edibles.
