Smuggling
Smuggling is the act of moving drugs from one city to another via Morticians.
Morticians
To smuggle drug as a Mortician you have to be at least Mortician Assistant. In a normal case, a gangster will approach you to smuggle drugs for him and place an offer. In order to accept the offer, you need to be in the same city as the gangster when he makes the offer. When he sends the offer, you will receive a Request in your Request/Offers journal - if you choose to do the job, you may accept it.
After you have accepted the job, you need to wait until the gangster is in the destination city before you smuggle the drugs. Once you have confirmed that the gangster is at the correct location, you may proceed to sending the drugs via Income -> Aggravated Crimes -> Smuggle Drugs at the Funeral Parlour. Note that you will need your Agg Timer ready as well in order to ship the drugs out. You will also notice that in this menu, there are two different options to choose from; "Sell Drugs to Local Dealer" and "Smuggle the Drugs to a city as the deal described." The first option allows you to sell the drugs immediately, making you some money - however, doing so will most likely result in your death.
Note: There is a small chance that you will be busted during the smuggle - there is nothing you or the gangster can do about it.
Once you have completed smuggling the drugs, you may proceed to collecting your fee from the gangster at the agreed amount. Usual fee taken is $1,000 Dirty Cash which is received when the gangster sends the offer and $10,000-$20,000 in clean cash after the trade is complete.
