Drug Units
Drug units is how many units of drugs you can carry. Yup. You gain drug units by buying and selling drugs you are already able to carry and gaining experience through doing jails and posting in the forums.
Units
Drug Units are two things really: The number of Drugs you are allowed to hold, and a ranking requirement. Drug Units are gained through game experience. In order to see if you can gain more units you have to 'Sell Drugs'. You can tell if you are ready to gain more units by going to your profile. The number (in parenthesis) is the number of units you should be able to hold. The number before it is what you are actually able to hold at that moment.
Gaining Units
Units are gained through a wide variety of methods - not all of which will be made immediately apparent. The simplest way to gain units is to commit Petty and Felony crimes. Another simple way is through Jail Breaking. Some better ways to gain drug units are to actually deal drugs themselves, post in the streets and in businesses, and attack fortifications of dead leaders or TylerDurden - all of which are tremendous bonuses to your experience points needed to attain higher unit counts.
Getting Past 20 Units
In order to get the nod to carry anything more than 20 units you will need to bribe your local FBN agent. You accomplish this by going to the Tips section and tipping the FBN agent many times until he tells you that you are starting to understand how your 'relationship' works. After that you should be able to gain some more, provided you have the required experience points to back it up. Drug Units.
