As you said in the topic,here's the cmds.
But next time post in correct section.

pawn Код:

//you need zcmd include also.
new heroin[MAX_PLAYERS];
CMD:loadheroin(playerid,params[])
{
 #pragma unused params
   new Float:x,Float:y,Float:z
   GetPlayerPos(playerid,x,y,z);
   heroin[playerid]=1;
   GivePlayerMoney(playerid,-3000);
   SetPlayerPos(playerid,xpos,ypos,zpos);//Replace Xpos, Ypos, Zpos with your coordinate.
   SendClientMessage(playerid,0xFF0000,"Herion Loaded");
   return 1;
} 

CMD:unloadheroin(playerid,params[])
{
 #pragma unused params
   if(heroin[playerid] == 0)
   return SendClientMessage(playerid,0xFF0000,"You haven't loaded heroin");
   SetPlayerPos(playerid,x,y,z);
   SendClientMessage(playerid,0xFF0000,"Heroin Unloaded");
   GivePlayerMoney(playerid,-10000);
   heroin[playerid]=0;
   return 1;
}

Sorry if mistakes are there because I did this through mobile.
