Heroin

The heroin is a part of Grand Theft Auto IV's storyline including The Lost and Damned and The Ballad of Gay Tony. Like the diamonds, it also has a large part of the game that involves the protagonists Niko, Johnny and Luis. Below are scenarios that takes place involving different people that gain possession of the heroin and the heroin itself.

Arrival in Libert City, Angels of Death theft and Elizabeta's attempt to offload it
When the Platypus arrived in Liberty City, the heroin, which was the Triads, was smuggled into the city together with the diamonds and Niko Bellic. The Angels of Death soon stole it, and it was in their hands until Johnny Klebitz and The Lost Brotherhood came, destroyed the AoD clubhouse and stole it themselves. The Lost, along with Elizabeta Torres tried to offload the heroin, but the deal turned out to be a LCPD sting. Niko Bellic and Playboy X managed to escape, Johnny also escaped with the heroin and took it back to the Lost MC clubhouse.

The Lost MC's attempt to sell it to the Triads
The Lost MC decide they will try and sell the heroin back to the triads. Billy Grey tells Johnny and Jim to do the deal. Billy had previously conspired with the Triad leader to kill Johnny once he arrived, and while Johnny and Jim are being jumped, the police arrive and arrest Billy. Johnny, Jim and Brian Jeremy escape while the Triads take back their heroin. In a side note, Luis Lopez and Tony Prince had previously met with the triad leader to discuss some licencing arrangemnts for the planning department on behalf of Rocco Pelosi.

Phil Bell and Niko Bellic's involvement
Phil Bell of the Pegorino's hires Niko Bellic to ambush the triads and steal the heroin before they can ship it. Niko does so and hijacks the truck, then transports it to Bell's nephew's house. After a week or so, Niko and Phil went to the house to move the heroin, however, the house was being monitored by the FIB. The three of them fought numerous members of the NOOSE before hiding the heroin.

Eventually, Jimmy Pegorino made a deal with Dimitri Rascalov, and asked Niko to accompany Phil when overseeing the deal. Niko, is reluctant due to his personal grudge against Dimitri, but Jimmy manages to talk him round. However, Niko is again left unsure when Roman urges him to do the deal, and Kate, Niko's potential girlfriend tells him he would lose her respect if Niko made a deal with a man who previously betrayed him. Niko, then either makes a deal, or takes his revenge.

Deal
If Niko does the deal with Dimitri, Dimitri kills the buyer's, and takes the heroin and escapes. Phil and Niko pursue one of his men with the money and retrieve it. Dimitri delivers the heroin to Bulgarin, and it is unloaded at Funland. Dimitri is then killed by Niko by, while Luis Lopez goes to Funland in pursuit of Blugarin, he destroys the heroin and kills Bulgarin on his private jet.

Revenge
If Niko chooses to take revenge, he carries out a full blown ambush and slaughters Dimitri's men on the Platypus, which Dimitri is using to import/export the heroin. After killing Dimitri, Niko leaves the scene. Bulgarin and Timur claim the heroin since Dimitri is dead, and then take it to Funland to be unloaded. Again Luis Lopez arrives and destroys it, and kills Bulgarin soon after, around the same time Niko chases Pegorino to Happiness Island where he kills him, avenging Kate's murder.

Niko Bellic
After the Triads took back their Heroin, because of the police attention, they think it's cursed. So Niko under orders from Phil Bell steals the heroin and hides it in a abandoned house. When Niko and Phil went to go pick up the heroin, the FIB attempt to bust them, proving that the heroin is being watched, therefore cursed. After they escaped the FIB, the Pegorinos ally with the Russians and try to sell it to another Mafia Family. But Dimitri kills the buyers and steals the heroin for himself in the "Deal" ending whilst in the "Revenge" ending it is left with the Pegorino's.

Johnny Klebitz
The heroin they steal from the Angels of Death Clubhouse actually has huge consequences that last to the end of the game. First off, when Johnny, Playboy X and Niko try to sell it to UC, the NOOSE ambush them. After that a man named Agent Jones calls Johnny and everyone in the club to give information about the club. This must have been where Billy agrees, telling the Triad Boss to rip off and kill Johnny and Jim in This Shit's Cursed, however, the Triad Boss betrayes Billy Grey and gets himself arrested and Brian Jeremy thought Johnny called the cops. This is were Brian gathers alot of Lost bikers and The Lost start to implode. The civil war gets many bikers killed and not many are in the club. And eventually leads to Billy to rat out his brothers.

Luis Lopez
(DEAL) After Dimitri was killed, Bulgarin claimed the heroin, Luis destroyed all of the heroin, and killed Bulgarin soon after.

(REVENGE) After Pegorino was killed the heroin was sold to Bulgarin, Luis destroyed all of the heroin, and killed Bulgarin soon after.
