I had a suggestion for the system a while ago:
Official gangs having the ability to dynamically create labs inside properties owned by certain ranked members of the faction. If LSPD finds and destroys it they can't place it there anymore, and have a 1 week cooldown before they may place it elsewhere and produce again. The drugs would be sold only to players.
As for the effects on the drugs, yeah they could use some tweaking and benefits though are mainly used for RP purposes right now which I personally prefer more anyway. Though it has been said many times over that the people want more benefits to something that is otherwise useless. Henceforth we will again (yes we dicussed this before) discuss what sort of effects would be given by each drug.
Thanks for the suggestion.
