Drug Front Properties
When you invest in drug front properties you are paying for drug to be distributed in your home city. The higher you rank the better drug you can create and distribute. Every 24 hours you will produce new drugs. That is if the old drugs are gone so you have room for the new ones. Once you have produced your drugs you can set a price to be bought by the public. In order to keep yourself out of jail you need to bribe the FBN officer on the payroll. You can bribe him at least once every 48 hours at minimum. The first person to buy the drugs gets the drugs. There are only limited amounts of drug per city. There will be more released depending on how large the population is

thanks for the info...
