The Official Dealer McDope Dealing Game (1971)

From the rules:

"Leave Doobietown, U.S.A. and journey to an intriguing port of call, score caches of dope and return home anxious to sell. Sounds simple and it is - as long as karma, skill and the roll of the dice are on your side and you don't get hassled at any borders, ripped off by your partners or busted. Yeh, busted. Lots of dealers go to jail. In fact, there are 500 "busted gringos" sitting in Mexican jails right now.

Yes, dealing is a high risk / high gain situation. Remember all dealers play hard, but they don't all play fair. When in doubt ask yourself what McDope would do if he were there."
