[Damn Right M.I.A!]

Yes.
code:

pawn Код:

public OnPlayerCommandText(playerid, cmdtext[])
{
    new cmd[128], idx;
    cmd = strtok(cmdtext, idx);
 
    if(strcmp(cmd, "/checkdrunk", true) == 0)
    {
        new tmp[128], drunkz0r;
        tmp = strtok(cmdtext, idx);
 
        if(strlen(tmp) == 0) return SendClientMessage(playerid, 0xFFFFFFFF, "USAGE: /checkdrunk [playerid]");
 
        GetPlayerDrunkLevel(strval(tmp));
        if(drunkz0r > 0)
        {
         SendClientMessageToAll(0xFFFFFFFF, "w000t someone is drunk!!!11one!11");
        }
        return 1;
    }
    return 0;
}

Should work
correct me if I'm wrong.
