Ory,
Typically here, in the States, the only thing available in a store, let's say Wal-Mart, is mace. It's a watered down version of true pepper spray. OC, which is what we have at work and what police carry, is a 10% pepper 'juice' oil based spray. We can carry foam, spray or stream...up to us. The foam sticks to the face (or wherever it hits:rolleyes:) and dyes the skin an orange color. The foam is nice because it spreads like shaving cream, you can also spray it into your own hand and smear it across someone's eyes. Sounds a bit much but when you have to fight in close quarters and don't want to spray your partner, that comes in handy. ;)
Self-defense classes are good...so is Judo (if you're looking into one of the martial arts). Judo teaches you more grappling and ground fighting than the other disciplines I do believe.
Anyway... :) None of it is illegal here, you just don't find the OC as readily accessible. It's sold through police supply magazines and at uniform stores and such.
