So I guess the title says it all, my idea is that there be a chance you get drugs instead of cash if you have open units for drugs.. 

First, why not both?

Second, I doubt anybody would be carrying pounds in their pocket :/

I do love the concept though.

Maybe another option for drugs, like "raid a drug house" or something along those lines.

I like the idea but how would this work. Would you get the money for there drugs or would it add there units onto yours so you will be carrying your own and the victims until you sell them?

I would like to see mugging back and if you are train it up you can take drugs and even there gun, it would bring different tactics to a war.

What about a raid on a DFP?

well, think of it this way, when you grab a purse, you get the cash and the lipstick, plus what ever else we're carrying, so, say your carting a bag of weed around, say 5 units in a duffle bag, and some one comes by and grabs your bag... Goodbye drugs, goodbye wallet. And who ever just grabbed it has 5 more pounds of weed...

now its not like they're able to carry extra drugs, but if they're carrying a full load already, they go threw a quick sale page and sell the extra at current city value, high or low, or dump the drugs, where they might be able to come back too... Or some one might be able to find it on there own.

hell, if you wanted, you could spent extra cash on the drugs to buy a backpack or temp body guard (not like the kind CLs buy and maintain, this would be paid for every time you bought drugs and went away when you sold them.) both would make it harder to snag the bag at least.

Maybe instead of picking pockets, it'll be mugging again... But rival gangs would be doing this.
