I'm going to have to argue against using a pill made from weed by a pharma or a "nutrition" company in this case.

When using a whole plant to make an extract or an oil you are using all the cannibanoids. When making a pill you get a refined cannibanoid, which, can cause adverse reactions, or even just be the wrong cannibanoid (which can make it not work or be less effective).

Part of the reason this plant works well on pain and other things has to do with the entire plant. Not just 1 or 2 things (which pill companies seem to just use 1 or 2 of the compounds which makes up the pain killer, anti inflamatory etc responses)

Arguably the most popular and quickest way is to smoke the bud, waxes or oils. However you can eat most of those which can give you the same effect (reason for the cookies and whatnot) but eating it isn't popular due to dosage issues (you don't feel it immedately so people tend to take too much)
