Now, about potentially dangerous pastimes in Star Wars. Han Solo is a drug runner, plain and simple: Glitterstim spice is a hallucenogenic drug and Han made his fame smuggling it from Kessel past Imperial blockades. Not to mention all the talk in the EU of him and Lando being gamblers, that's how the Falcon changed hands. (Han was a pretty dangerous character, after all, he shot first at Greedo

). The Arconan race is succeptible to addiction to plain old table salt, and of course there were "Death Stick" dealers all over Coruscant. Drugs, gambling and other bad things are a part of the Star Wars universe.
Now, do I think they should use them to sell lottery tickets, probably not, and while Lucasfilm is a lot more mindful of spin-offs and licensing now than they were in the late 70's (Splinter of the Minds Eye and the Holiday Special?), any operation the size of Lucas Licensing could make a mistake once in a while.
