Easy, use SetPlayerSpecialAction!

pawn Code:

if(strcmp("/smoke", cmd, true) == 0)
    {
        SetPlayerSpecialAction(playerid, SPECIAL_ACTION_SMOKE_CIGGY);
        GivePlayerMoney(playerid, -2);
        return 1;
    }

Tada!!! When you write /smoke it takes 2 money and gives a cig, comment ( // ) GivePlayerMoney part if you want cigs to be free or just delete it, also search the wiki for more info about SetPlayerSpecialAction

I was really bored and people playing my server asks how I get cigs with a command
